The clinician should be aware that patients with longstanding hypertension and cerebrovascular disease are at increased risk of a cerebrovascular accident. (medscape.com)
Remember that not all "down" or recumbent patients have neurologic disease. (vin.com)
Since the majority of patients with neurologic disease as the cause of their abnormal gait have a neurologic deficit, the neurologic examinationplays a crucial role in their evaluation. (vin.com)

My sustaining research interest/s are the pathogenesis of infectious disease and population responses. (massey.ac.nz)
Numerous investigational therapies, many of which are currently in clinical trials like stem cell transplant for ALS , have been developed in response to recent advancements in our knowledge of the disease pathogenesis processes that underlie ALS. (selfgrowth.com)

If the brain is the command center, then the neurons are the tiny messengers- taking the signals to various parts of the body and also bringing back information to the headquarters-forming the nervous system (along with "glial cells" that support the neurons). (mndtrust.co.in)
The Soma is the cell body of the neuron while the tiny projections called Dendrites receive signals and the long arm-like protrusion called the Axon takes the signal away from the cell to the next cell. (mndtrust.co.in)
As a motor neuron matures, it develops an axon, which is used for its main function of transmitting signals long distances across the body. (pluto.bio)
Within about 18 days, the undifferentiated cells we started with will have become mature motor neurons which can form connections and send signals to each other (see image below). (pluto.bio)

An attorney should be consulted regarding a "living will," and power of attorney should be established prior to the terminal phase of this ultimately fatal disease. (medscape.com)

In this podcast, researchers at MIT look at the ability of high frequency light stimulation to reduce amyloid plaques and improve memory in Alzheimer's Disease. (bartleby.com)
Alzheimer's disease (AD) is the most common NDD, affecting an estimated 5 million Americans. (aao.org)

The pathological hallmarks comprise loss of motor neurons with intraneuronal ubiquitin-immunoreactive inclusions in upper motor neurons and TDP-43 immunoreactive inclusions in degenerating lower motor neurons. (orpha.net)

Additionally, the death of motor neurons may be slowed, delaying the loss of motor function. (selfgrowth.com)
