PATHOPHYSIOLOGY 1: NEUROLOGICAL DISORDERS
QUESTIONS WITH DETAILED VERIFIED AND 100%
ACCURATE ANSWERS
What is Dementia? Correct Answers acquired deterioration and
progressive failure of cerebral functioning.
- Memory, intellect, awareness and language are lost.
What are the pathophysiological mechanisms to Dementia? Correct
Answers Neuronal degeneration- neurons in the cervical cortex, basal
ganglia, and spinal cord start to deteriorate.
Brain Atrophy- The brain starts to lose weight in the grey matter
Atherosclerosis- Very common vascular disease. Whereby the arteries
everywhere in the body become altered and harder which causes
hypoxia.
Brain Trauma- can cause long or short-term effects. Eg. concussion
Brain Tissue compression- space occupying injuries causes compression
on the brain and affects the cerebral cortex.
What can cause Dementia? Correct Answers infection
IIP
Nutritional deficiencies
chronic drug intoxication- alcohol (preventable)
Metabolic disorders
Tumors- Frontal an temporal
pharmacological side effects- antihypertensives
, Neurodegenerative disorders- AD, Parkinsons (irreversible)
Vascular disease- vascular dementia (Irreversible)
What is Alzheimer's disease (AD)? Correct Answers a progressive
degenerative disease of the brain that results in dementia
- brain showa areas with neuritic plaques (neurons inside are most likely
dead or are injured.), amyloid protein deposits, neurofibrillary tangles,
neuronal degeneration
TRUE OR FALSE? You can see AD on an MRI? Correct Answers
TRUE
What are symptoms usually connected to AD? Correct Answers
memory loss, confusion and disorientation, low ability to concentrate.
What occurs in the brain when someone has AD? Correct Answers -
Hemisphere shrinks
- Cerebral cortex shrinks ( becomes very thin less than 1cm)
- Enlarged ventricles
- Hippocampus shrinks
What are risk factors for AD? Correct Answers advanced age (65+)
traumatic brain injury
infection- meningitis
atherosclerosis
