A rare form of DEMENTIA that is sometimes familial. Clinical features include APHASIA; APRAXIA; CONFUSION; ANOMIA; memory loss; and personality deterioration. This pattern is consistent with the pathologic findings of circumscribed atrophy of the poles of the FRONTAL LOBE and TEMPORAL LOBE. Neuronal loss is maximal in the HIPPOCAMPUS, entorhinal cortex, and AMYGDALA. Some ballooned cortical neurons contain argentophylic (Pick) bodies. (From Brain Pathol 1998 Apr;8(2):339-54; Adams et al., Principles of Neurology, 6th ed, pp1057-9)
The classic infantile form of Niemann-Pick Disease, caused by mutation in SPHINGOMYELIN PHOSPHODIESTERASE. It is characterized by accumulation of SPHINGOMYELINS in the cells of the MONONUCLEAR PHAGOCYTE SYSTEM and other cell throughout the body leading to cell death. Clinical signs include JAUNDICE, hepatosplenomegaly, and severe brain damage.
Microtubule-associated proteins that are mainly expressed in neurons. Tau proteins constitute several isoforms and play an important role in the assembly of tubulin monomers into microtubules and in maintaining the cytoskeleton and axonal transport. Aggregation of specific sets of tau proteins in filamentous inclusions is the common feature of intraneuronal and glial fibrillar lesions (NEUROFIBRILLARY TANGLES; NEUROPIL THREADS) in numerous neurodegenerative disorders (ALZHEIMER DISEASE; TAUOPATHIES).
An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.
Neurodegenerative disorders involving deposition of abnormal tau protein isoforms (TAU PROTEINS) in neurons and glial cells in the brain. Pathological aggregations of tau proteins are associated with mutation of the tau gene on chromosome 17 in patients with ALZHEIMER DISEASE; DEMENTIA; PARKINSONIAN DISORDERS; progressive supranuclear palsy (SUPRANUCLEAR PALSY, PROGRESSIVE); and corticobasal degeneration.
A degenerative disease of the central nervous system characterized by balance difficulties; OCULAR MOTILITY DISORDERS (supranuclear ophthalmoplegia); DYSARTHRIA; swallowing difficulties; and axial DYSTONIA. Onset is usually in the fifth decade and disease progression occurs over several years. Pathologic findings include neurofibrillary degeneration and neuronal loss in the dorsal MESENCEPHALON; SUBTHALAMIC NUCLEUS; RED NUCLEUS; pallidum; dentate nucleus; and vestibular nuclei. (From Adams et al., Principles of Neurology, 6th ed, pp1076-7)
A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)
Abnormal structures located in various parts of the brain and composed of dense arrays of paired helical filaments (neurofilaments and microtubules). These double helical stacks of transverse subunits are twisted into left-handed ribbon-like filaments that likely incorporate the following proteins: (1) the intermediate filaments: medium- and high-molecular-weight neurofilaments; (2) the microtubule-associated proteins map-2 and tau; (3) actin; and (4) UBIQUITINS. As one of the hallmarks of ALZHEIMER DISEASE, the neurofibrillary tangles eventually occupy the whole of the cytoplasm in certain classes of cell in the neocortex, hippocampus, brain stem, and diencephalon. The number of these tangles, as seen in post mortem histology, correlates with the degree of dementia during life. Some studies suggest that tangle antigens leak into the systemic circulation both in the course of normal aging and in cases of Alzheimer disease.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Lower lateral part of the cerebral hemisphere responsible for auditory, olfactory, and semantic processing. It is located inferior to the lateral fissure and anterior to the OCCIPITAL LOBE.
Hereditary and sporadic conditions which are characterized by progressive nervous system dysfunction. These disorders are often associated with atrophy of the affected central or peripheral nervous system structures.

Semantic dementia with ubiquitin-positive tau-negative inclusion bodies. (1/46)

Three cases are reported with dementia and ubiquitin-positive but tau-negative inclusion bodies. All patients had a semantic dementia and the clinical details of two of these have been published as the first description of a selective semantic memory impairment. The original diagnosis had been of Pick's disease based on frontotemporal atrophy, but re-examination has revealed ubiquitin-positive but tau-negative inclusions as well as neurites in the frontotemporal cortices and ubiquitin-positive, intracytoplasmic inclusions in the granule cells of the dentate fascia. These inclusions are identical to those reported in association with amyotrophic lateral sclerosis (motor neuron disease), but none were seen in brainstem or spinal cord motor neurons.  (+info)

Structural analysis of Pick's disease-derived and in vitro-assembled tau filaments. (2/46)

Pick's and Alzheimer's diseases are distinct neurodegenerative disorders both characterized in part by the presence of intracellular filamentous tau protein inclusions. The tight bundles of paired helical filaments (PHFs) of tau protein found in Alzheimer's disease (AD) differ from the tau filaments of Pick's disease in their morphology, distribution, and pathological structure as identified by silver impregnation. The filaments of Pick's disease are loosely arranged in pathognomonic spherical inclusions found in ballooned neurons, whereas the tau pathology of AD is classically described as a triad of neuropil threads, neurofibrillary tangles, and dystrophic neurites surrounding and invading plaques. In this study we used the high-resolution technique of scanning transmission electron microscopy to characterize and compare the filaments found in Pick's disease with those found in AD. In addition, we determined the mass/nm length and density of arachidonic acid-induced in vitro-assembled filaments. Three morphologically distinct populations of Pick's filaments were identified but each was indistinguishable from AD-PHFs in mass/nm length and density. Filaments assembled in vitro from single isoforms were similar in mass/nm length, but less dense than AD-PHFs and Pick's disease filaments. Finally, we provide clear structural evidence that a PHF, whether found in disease or assembled in vitro, is composed of two distinct intertwined filaments.  (+info)

Classic Pick's disease type with ubiquitin-positive and tau-negative inclusions: case report. (3/46)

We report on a patient presenting Pick's disease similar to the one reported by Pick in 1892, with ubiquitin-positive and tau-negative inclusions. His diagnosis was made on the basis of clinical (language disturbance and behavioural disorders), neuropsychological (progressive aphasia of the expression type and late mutism), neuroimaging with magnetic resonance (bilateral frontal and temporal lobes atrophy) and brain single photon emission computed tomography (frontal and temporal lobes hypoperfusion) studies. Macroscopic examination showed atrophy on the frontal and temporal lobes. The left hippocampus displayed a major circumscribed atrophy. The diagnostic confirmation was made by the neuropathological findings of the autopsy that showed neuronal loss with gliosis of the adjacent white matter and apearance of status spongiosus in the middle frontal and especially in the upper temporal lobes. There were also neuronal swelling (ballooned cell) and argyrophilic inclusions (Pick's bodies) in the left and right hippocampi. Anti-ubiquitin reaction tested positive and anti-tau tested negative.  (+info)

Proton chemical shift imaging in pick complex. (4/46)

BACKGROUND AND PURPOSE: Pick complex (PC) is the name given to a group of diseases comprising Pick disease and its variations, all of which have a large degree of pathologic and clinical overlap. Because of this overlap, the observation of neuropathologic changes in vivo is difficult, although these changes play important roles in the criteria used for classification. The purpose of this study was to evaluate changes in brain metabolism in PC with proton chemical shift imaging ((1)H-CSI). METHODS: Nine patients with PC (three each with frontotemporal dementia, corticobasal degeneration [CBD], and primary progressive aphasia [PPA]) and five healthy subjects underwent (1)H-CSI. Volumes of interest were selected at the level of the basal ganglia by using a spin-echo sequence (TR/TE, 2000/13). Peak areas and ratios of N-acetylaspartate (NAA), creatine (Cr), and choline (Cho) were calculated in voxels in the basal ganglia and perisylvian regions. RESULTS: Reduced NAA/Cho ratios were observed in the right basal ganglia of the patients with PC. In patients with CBD or PPA, low NAA/Cr values were detected in the right perisylvian region. CONCLUSION: In PC, (1)H-CSI decreased NAA values in a wide area. Significantly reduced NAA levels in the right hemisphere in patients with PC suggests a neurodegenerative change and may reflect cases in which the right hemisphere is dominantly affected, compared with the left hemisphere. (1)H-CSI provided information that could not be obtained with other imaging techniques. Thus, (1)H-CSI may provide useful information for understanding the pathologic process underlying PC.  (+info)

Biochemical analysis of tau proteins in argyrophilic grain disease, Alzheimer's disease, and Pick's disease : a comparative study. (5/46)

Although argyrophilic grain disease is characterized histopathologically by tau-positive lesions known as argyrophilic grains located predominantly in limbic brain regions in the absence of other diagnostic neuropathologies, the biochemical correlates of argyrophilic grains in gray and white matter have not been reported. Thus, we analyzed insoluble (pathological) tau proteins in five argyrophilic grain disease brains in comparison with those seen in Alzheimer's disease and Pick's disease. Analyses of separately dissected gray and white matter samples from various cortical regions revealed that pathological tau in argyrophilic grain disease was confined primarily to mediotemporal neocortical gray and adjacent white matter, and also to the allocortex, amygdala, and hippocampus. The amounts of sarcosyl-insoluble tau in all five cases were substantially lower than in Alzheimer's disease and Pick's disease, but the amounts of sarcosyl-insoluble tau in white matter were higher or comparable to that detected in gray matter from the same region, which distinguishes argyrophilic grain disease from Alzheimer's disease. The banding patterns of tau isoforms in argyrophilic grain disease varied: in three cases they were similar to Alzheimer's disease, but in two other cases, 4 microtubule binding repeat (4R) tau predominated, which distinguishes argyrophilic grain disease from classical Pick's disease. The differences between these three diseases were re-enforced by the predominance of straight tau filaments from argyrophilic grain disease brains. Thus, we conclude that argyrophilic grain disease is a distinct tauopathy characterized by prominent accumulation of argyrophilic grains in limbic brain regions in association with the characteristic tau biochemical and ultrastructural profile reported here.  (+info)

Severity of gliosis in Pick's disease and frontotemporal lobar degeneration: tau-positive glia differentiate these disorders. (6/46)

Frontotemporal dementia is a term used to characterize diverse neuropathological conditions that can present with the same clinical phenotype. Five different neuropathologies underlie this disorder. However, consistent frontal and/or temporal neuronal loss and gliosis characterize all cases, the majority having no obvious pathological inclusions. Because neuronal loss and gliosis are consistent features across all cases, the present study aimed to determine the relationship between neuronal loss, gliosis and, for cases with abnormal tau inclusions, intracellular tau deposition. Formalin-fixed brain specimens from sporadic cases with frontotemporal dementia (eight with tau-positive Pick bodies, five with frontotemporal lobar degeneration without inclusions) were compared with those from non-diseased controls (n = 5). Brain specimens were cut into 3 mm coronal slices for evaluation and tissue samples from the superior frontal gyrus were taken for microscopic analysis. Immuno histochemistry for glia-specific proteins (astrocytic glial fibrillary acidic protein and microglial major histocompatibility complex II) and different tau epitopes was performed on 50 microm free-floating sections. Gross patterns of brain atrophy were analysed and upper and lower layer pyramidal neurons and glial cell numbers were quantified. A disease severity scheme was devised using the degree of gross macroscopic frontal and temporal atrophy to establish the relationship between the gliosis and neurodegeneration. In this small sample, the patterns of gross atrophy could be grouped reliably into four stages of severity. These stages were the same across disease groups and correlated with volume- corrected pyramidal neuron densities. In cases with Pick bodies, disease stage also correlated with duration, providing further evidence that these stages represent the progression of degeneration in this limited sample. Whereas there were, on average, many more reactive astrocytes in the cases with Pick bodies than in those with frontotemporal lobar atrophy, there was significant overlap between cases in the degree of astrocytosis. However, a large proportion of the astrocytes in Pick's disease displayed phosphorylated tau immunoreactivity, whereas no tau-positive astrocytes were found in frontotemporal lobar degeneration. The pattern and degree of microglia activation were similar in all the dementia cases analysed, with considerably more activated microglia accumulating in white matter. In this small sample, the abundance of white matter microglia at early disease stages suggests a prominent role for this cell type in the neurodegenerative process. In frontotemporal lobar degeneration, a significant proportion of the activated white matter microglia were tau-2-immunoreactive, suggesting direct involvement in axonal degeneration, possibly via immune processes.  (+info)

Alterations of muscarinic acetylcholine receptors in atypical Pick's disease without Pick bodies. (7/46)

BACKGROUND: Atypical Pick's disease without Pick bodies is a type of frontotemporal dementia characterised by semantic dementia and temporal dominant lobar atrophy with ubiquitinopathy. No neurochemical analyses have ever been reported in this condition. OBJECTIVE: To investigate muscarinic acetylcholine receptors (mAchR) and their subtypes (M1-M4) in atypical Pick's disease. SUBJECTS: Five cases of atypical Pick's disease were studied. They were compared with nine control cases, 11 cases of Alzheimer's disease, and seven cases of dementia with Lewy bodies. METHODS: A [(3)H]quinuclidinyl benzilate (QNB) binding assay and an immunoprecipitation assay using subtype specific antisera were used. RESULTS: The total amount of mAchR in the temporal cortex was lower in atypical Pick's disease than in controls or Alzheimer's disease cases, but there were no significant differences between the three groups in the frontal cortex. In the temporal cortex, there was a smaller proportion of M1 receptors in atypical Pick's disease than in the controls or in the patients with Alzheimer's disease and dementia with Lewy bodies. In contrast, the proportion of M2 receptor was higher in atypical Pick's disease than in the other three groups. CONCLUSIONS: Depletion of postsynaptic cholinoreceptive neurones in the temporal cortex is more severe in atypical Pick's disease than in other neurodegenerative dementing disorders.  (+info)

Nitration of tau protein is linked to neurodegeneration in tauopathies. (8/46)

Oxidative and nitrative injury is implicated in the pathogenesis of Alzheimer's disease (AD) and Down syndrome (DS), but no direct evidence links this type of injury to the formation of neurofibrillary tau lesions. To address this, we generated a monoclonal antibody (mAb), n847, which recognizes nitrated tau and alpha-synuclein. n847 detected nitrated tau in the insoluble fraction of AD, corticobasal degeneration (CBD), and Pick's disease (PiD) brains by Western blots. Immunohistochemistry (IHC) showed that n847 labeled neurons in the hippocampus and neocortex of AD and DS brains. Double-label immunofluorescence with n847 and an anti-tau antibody revealed partial co-localization of tau and n847 positive tangles, while n847 immunofluorescence and Thioflavin-S double-staining showed that a subset of n847-labeled neurons were Thioflavin-S-positive. In addition, immuno-electron microscopy revealed that tau-positive filaments in tangle-bearing neurons were also labeled by n847 and IHC of other tauopathies showed that some of glial and neuronal tau pathologies in CBD, progressive supranuclear palsy, PiD, and frontotemporal dementia with parkinsonism linked to chromosome 17 also were n847-positive. Finally, nitrated and Thioflavin-S-positive tau aggregates were generated in a oligodendrocytic cell line after treatment with peroxynitrite. Taken together, these findings imply that nitrative injury is directly linked to the formation of filamentous tau inclusions.  (+info)

Pick's disease, also known as Frontotemporal dementia (FTD), is a rare form of degenerative brain disorder that affects the frontal and temporal lobes of the brain. It is characterized by progressive shrinkage (atrophy) of these regions, resulting in a decline in cognitive abilities, behavioral changes, and language difficulties.

The medical definition of Pick's disease includes the following key features:

1. Progressive deterioration of cognitive functions, including memory, judgment, and problem-solving skills.
2. Changes in personality, emotional blunting, and loss of social inhibitions.
3. Language difficulties, such as difficulty with word finding, grammar, and comprehension.
4. Presence of abnormal protein deposits called Pick bodies or Pick cells in the affected brain regions.
5. Exclusion of other causes of dementia, such as Alzheimer's disease, vascular dementia, or Lewy body dementia.

Pick's disease typically affects people between the ages of 40 and 60, and it tends to progress more rapidly than other forms of dementia. Currently, there is no cure for Pick's disease, and treatment focuses on managing symptoms and improving quality of life.

Niemann-Pick Disease, Type A (NPD A) is a rare inherited metabolic disorder caused by a deficiency of the enzyme acid sphingomyelinase (ASM). This enzyme defect results in the accumulation of lipids, particularly sphingomyelin and cholesterol, within various cells of the body, including brain cells, liver cells, and white blood cells.

The accumulation of these lipids leads to progressive damage to these organs, causing a range of symptoms such as an enlarged liver (hepatomegaly), anemia, jaundice, and neurological problems like developmental delay, seizures, loss of muscle tone, and difficulty with swallowing. NPD A is typically diagnosed in infancy or early childhood and is often fatal by around two to three years of age due to severe neurological complications. It is an autosomal recessive disorder, meaning that an individual must inherit two copies of the defective gene (one from each parent) to develop the condition.

Tau proteins are a type of microtubule-associated protein (MAP) found primarily in neurons of the central nervous system. They play a crucial role in maintaining the stability and structure of microtubules, which are essential components of the cell's cytoskeleton. Tau proteins bind to and stabilize microtubules, helping to regulate their assembly and disassembly.

In Alzheimer's disease and other neurodegenerative disorders known as tauopathies, tau proteins can become abnormally hyperphosphorylated, leading to the formation of insoluble aggregates called neurofibrillary tangles (NFTs) within neurons. These aggregates disrupt the normal function of microtubules and contribute to the degeneration and death of nerve cells, ultimately leading to cognitive decline and other symptoms associated with these disorders.

Dementia is a broad term that describes a decline in cognitive functioning, including memory, language, problem-solving, and judgment, severe enough to interfere with daily life. It is not a specific disease but rather a group of symptoms that may be caused by various underlying diseases or conditions. Alzheimer's disease is the most common cause of dementia, accounting for 60-80% of cases. Other causes include vascular dementia, Lewy body dementia, frontotemporal dementia, and Huntington's disease.

The symptoms of dementia can vary widely depending on the cause and the specific areas of the brain that are affected. However, common early signs of dementia may include:

* Memory loss that affects daily life
* Difficulty with familiar tasks
* Problems with language or communication
* Difficulty with visual and spatial abilities
* Misplacing things and unable to retrace steps
* Decreased or poor judgment
* Withdrawal from work or social activities
* Changes in mood or behavior

Dementia is a progressive condition, meaning that symptoms will gradually worsen over time. While there is currently no cure for dementia, early diagnosis and treatment can help slow the progression of the disease and improve quality of life for those affected.

Tauopathies are a group of neurodegenerative disorders that are characterized by the abnormal accumulation and aggregation of the microtubule-associated protein Tau in neurons and glial cells. These misfolded Tau proteins form insoluble inclusions, such as neurofibrillary tangles (NFTs) and neuropil threads, which are associated with the degeneration and loss of neurons in specific regions of the brain.

Tauopathies include several well-known diseases, such as Alzheimer's disease (AD), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal dementia with Parkinsonism-17 (FTDP-17). The exact cause of Tauopathies remains unclear, but genetic mutations, environmental factors, or a combination of both may contribute to the development and progression of these disorders.

The accumulation of abnormal Tau aggregates is believed to play a central role in the neurodegenerative process, leading to cognitive decline, motor impairment, and other neurological symptoms associated with Tauopathies. The diagnosis of Tauopathies typically involves clinical evaluation, imaging studies, and sometimes postmortem examination of brain tissue. Currently, there are no effective disease-modifying treatments for Tauopathies, but ongoing research is focused on developing therapies that target Tau aggregation and clearance to slow down or halt the progression of these debilitating disorders.

Progressive Supranuclear Palsy (PSP) is a rare neurological disorder characterized by the progressive degeneration of brain cells that regulate movement, thoughts, behavior, and eye movements. The term "supranuclear" refers to the location of the damage in the brain, specifically above the level of the "nuclei" which are clusters of nerve cells that control voluntary movements.

The most common early symptom of PSP is a loss of balance and difficulty coordinating eye movements, particularly vertical gaze. Other symptoms may include stiffness or rigidity of muscles, slowness of movement, difficulty swallowing, changes in speech and writing, and cognitive decline leading to dementia.

PSP typically affects people over the age of 60, and its progression can vary from person to person. Currently, there is no cure for PSP, and treatment is focused on managing symptoms and maintaining quality of life.

Alzheimer's disease is a progressive disorder that causes brain cells to waste away (degenerate) and die. It's the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that disrupts a person's ability to function independently.

The early signs of the disease include forgetting recent events or conversations. As the disease progresses, a person with Alzheimer's disease will develop severe memory impairment and lose the ability to carry out everyday tasks.

Currently, there's no cure for Alzheimer's disease. However, treatments can temporarily slow the worsening of dementia symptoms and improve quality of life.

Neurofibrillary tangles are a pathological hallmark of several neurodegenerative disorders, most notably Alzheimer's disease. They are intracellular inclusions composed of abnormally phosphorylated and aggregated tau protein, which forms paired helical filaments. These tangles accumulate within the neurons, leading to their dysfunction and eventual death. The presence and density of neurofibrillary tangles are strongly associated with cognitive decline and disease progression in Alzheimer's disease and other related dementias.

The brain is the central organ of the nervous system, responsible for receiving and processing sensory information, regulating vital functions, and controlling behavior, movement, and cognition. It is divided into several distinct regions, each with specific functions:

1. Cerebrum: The largest part of the brain, responsible for higher cognitive functions such as thinking, learning, memory, language, and perception. It is divided into two hemispheres, each controlling the opposite side of the body.
2. Cerebellum: Located at the back of the brain, it is responsible for coordinating muscle movements, maintaining balance, and fine-tuning motor skills.
3. Brainstem: Connects the cerebrum and cerebellum to the spinal cord, controlling vital functions such as breathing, heart rate, and blood pressure. It also serves as a relay center for sensory information and motor commands between the brain and the rest of the body.
4. Diencephalon: A region that includes the thalamus (a major sensory relay station) and hypothalamus (regulates hormones, temperature, hunger, thirst, and sleep).
5. Limbic system: A group of structures involved in emotional processing, memory formation, and motivation, including the hippocampus, amygdala, and cingulate gyrus.

The brain is composed of billions of interconnected neurons that communicate through electrical and chemical signals. It is protected by the skull and surrounded by three layers of membranes called meninges, as well as cerebrospinal fluid that provides cushioning and nutrients.

The temporal lobe is one of the four main lobes of the cerebral cortex in the brain, located on each side of the head roughly level with the ears. It plays a major role in auditory processing, memory, and emotion. The temporal lobe contains several key structures including the primary auditory cortex, which is responsible for analyzing sounds, and the hippocampus, which is crucial for forming new memories. Damage to the temporal lobe can result in various neurological symptoms such as hearing loss, memory impairment, and changes in emotional behavior.

Neurodegenerative diseases are a group of disorders characterized by progressive and persistent loss of neuronal structure and function, often leading to cognitive decline, functional impairment, and ultimately death. These conditions are associated with the accumulation of abnormal protein aggregates, mitochondrial dysfunction, oxidative stress, chronic inflammation, and genetic mutations in the brain. Examples of neurodegenerative diseases include Alzheimer's disease, Parkinson's disease, Huntington's disease, Amyotrophic Lateral Sclerosis (ALS), and Spinal Muscular Atrophy (SMA). The underlying causes and mechanisms of these diseases are not fully understood, and there is currently no cure for most neurodegenerative disorders. Treatment typically focuses on managing symptoms and slowing disease progression.
