Q

Biological Background of Alzheimer’s

A

Excessive senile plaques (sphere-shaped deposits of beta-amyloid protein that form in the spaces between certain neurons and in certain blood vessels of the brain as people age) and neurofibrillary tangles (twisted protein fibers that form within certain neurons)

16
Q

What does Alzheimer’s include?

A

includes multiple cognitive deficits that develop gradually and steadily

17
Q

What disorders are comorbid with Alzheimer’s?

A

Anomia, Apraxia, Agnosia, Amnesia, Aphasia

18
Q

Prognosis of Alzheimer’s

A

cognitive deterioration is slow during the early and later stages but more rapid during middle stages

19
Q

Vascular Injury

A

+ when the blood vessels in the brain are blocked or damaged and no longer carry oxygen and other nutrients to certain areas of brain tissues, damage results
+ declines in speed of information processing and executive functioning

20
Q

Frontotemporal Degeneration

A

+ categorize a variety of brain disorders that damage the frontal or temporal regions of the brain – areas that affect personality, language, and behavior
+ declines in appropriate behavior or language

21
Q

Pick’s Disease (Frontotemporal Degeneration)

A

rare neurological condition that produces symptoms similar to Alzheimer’s, usually occurring in relatively early in life (40s or 50s)

22
Q

Traumatic Brain Injury

A

symptoms must persist for at least a week following the trauma, including executive dysfunction and problems with learning and memory

23
Q

Lewy Body Disease

A

+ Second most common neurocognitive disorder
+ involves the buildup of clumps of protein deposits called Lewy Bodies, within many neurons
+ Features significant movement difficulties, visual hallucinations, and sleep disturbances

24
Q

Prognosis of Lewy Body Disease

A

gradual and include impairment in alertness and attention, vivid visual hallucinations, and motor impairment

25
Q

Parkinson’s Disease

A

+ second most common neurodegenerative disorder
+ slowly progressive neurological disorder marked by tremors, rigidity, and unsteadiness
+ motor problems, tend to have stooped posture, slow body movements (bradykinesia), tremors, and jerkiness

26
Q

What can Parkinson’s Disease involve?

A

can also involve depression, anxiety, apathy, cognitive problems, and even positive symptoms

27
Q

Biological Background of Parkinson’s Disease

A

damage in dopamine pathways, loss of dopamine neurons in substantia nigra

28
Q

HIV Infection

A

+ HIV infection seems to be responsible for the neurological impairment
+ clumsy, repetitive movements, and become apathetic and socially withdrawn

29
Q

What are the early symptoms of neurological damage due to HIV Infection?

A

cognitive slowness, impaired attention, and forgetfulness

30
Q

What other name is neurological damage due to HIV Infection referred to?

A

Subcortical Dementia

31
Q

What are individuals with neurological damage due to HIV Infection more likely to experience?

A

more likely to experience depression and anxiety

32
Q

What does neurological damage due to HIV Infection involve?

A

involves various changes in the brain such as generalized atrophy, edema, inflammation, and patches of demyelination

33
Q

Substance-Use

A

+ use of different psychoactive
substances + poor diet
+ include memory impairment, aphasia, apraxia, agnosia, or disturbance in executive functioning

34
Q

Huntington’s

A

+ inherited progressive disease in which memory problems, along with personality changes and mood difficulties, worsen over time
+ rare degenerative disorder of CNS

35
Q

What is Huntington’s characterized by?

A

+ characterized by chronic, progressive chorea with subtle cognitive problems
+ Have movement problems too, such as severe twitching and spasms

36
Q

What is Huntington’s caused by?

A

+ caused by single dominant gene (Huntingtin Gene) on Chromosome 4
+ loss of cells in the basal ganglia and cortex

37
Q

What is Prion Disease caused by?

A

caused by prions (proteins that can reproduce and cause damage to brain cells leading to neurocognitive decline

38
Q

Is there any treatment for Prion Disease?

A

no treatment but not contagious

39
Q

Creutzfeldt-Jakob Disease (Type of Prion Disease)

A

symptoms include spasms of the body caused by slow acting virus that may live in the body for years before the disease develops
