Coma
Prolonged period of unconsciousness resulting from a disruption of the Reticular Formation within the Brain Stem
Amytrophic Lateral Sclerosis (ALS)
o A degenerative motor neuron disease causing muscular atrophy & weakness
o Usually strikes later in life (50's)
Multiple Sclerosis (MS)
A chronic slowly progressive disease of the central nervous system characterized by demyilinate patches called plaques.
Etiology is unknown
Dementia
An umbrella term for a group of pathological conditions characterized by progressive deterioration in several cognitive domains resulting from diffuse brain damage
Parkinsonism
A form of subcortical Dementia that is characterized by rigidity, slowness, mask-like faces, shuffling gait associated with degeneration of the Substantia Nigra in the Midbrain
Alzheimer's Disease
A form of Cortical Dementia due to atrophy of the Frontal and Temporal-Parietal lobes of the brain resulting in progressive, irreversible loss of memory, intellectual functions, apathy, speech and gait, disturbances and disorientation.
Alzheimer's Disease may be caused by
Changes in filament-like fibers (Neurofibrils) within neurons and the deposition of a particular substance known as "senile plaques"
Multi-infarct Dementia
A term used to describe a disease state characterized by dementia resulting from small infarctions (dead brain tissue) in persons with artery obstruction
Encephalitis
o Inflammation of the brain caused by a virus or metal poisoning
o May be transmitted through insect bites
Aphasia
An acquired impairment of language processes underlying receptive and/or expressive modalities caused by focal brain damage to areas of the brain primarily responsible for language function due usually to a Cerebral Vascular Accident
Traumatic Brain Injury (TBI)
Focal and/or diffuse damage to the brain caused by head trauma
Epilepsy
A recurrent disorder of cerebral function characterized by sudden attacks of altered consciousness & motor activity possibly due to microscopic lesions throughout the brain
Senescence
Not a disorder but rather the process of growing old including mental and physical weakness which accompanies the aging process
Prolonged period of unconsciousness resulting from a disruption of the Reticular Formation within the Brain Stem
