Question 1
Alzheimer’s disease can be an indication of dementia since; with time it gets worse and can
affect thought, language, and memory of a patient. Alzheimer's disease progressively causes
degeneration of brain cells causing them to waste away. This disorder causes a continuous
decline in thinking and disrupts patient’s ability to reason normally.
Multi-infarct dementia or vascular dementia is caused by a series of small strokes and it is often
associated with symptoms which develop gradually over a period of time. These strokes
contribute to brain damage particularly the area responsible for memory, learning, and language.
A brain infarct occurs when blood flow in the brain is blocked or interrupted.
Lewy bodies also cause a gradual deterioration in mental abilities. Protein deposits, referred to as
Lewy bodies occur in the brain nerve cells particularly in the areas associated in movement,
memory, and thinking. People with this condition also suffer from changes in alertness and
attention, and visual hallucinations.
Misuse of alcohol causes a severe deficiency of vitamin B-1 (thiamine) that eventually leads to
Korsakoff syndrome. Due to thiamine deficiency, the brain cells of a patient fail to generate
enough energy for proper functioning. Progressive damage of various brain features ultimately
leads to dementia.
Front Temporal Degeneration (FLTD) or Pick's disease is instigated by gradual impairment and
damage of nerve cells located in the temporal and frontal sections of the brain. For most of the
