MCQ Detailed View

Alzheimer’s disease is a chronic neurological disorder that primarily affects the brain, leading to progressive memory loss, confusion, and decline in thinking abilities. It is the most common cause of dementia, especially in elderly individuals, but it can also affect people in their mid-life in rare cases.

Nature of the Disease:

Alzheimer’s damages brain cells and disrupts the connections between neurons. This leads to difficulties in:

• 
  

  Memory retention (forgetting recent events, names, places).

  
  


• 
  

  Problem-solving and reasoning skills.

  
  


• 
  

  Language and communication abilities.

  
  


• 
  

  Daily activities and self-care.

  
  

The disease is linked to abnormal protein deposits in the brain:

• 
  

  Amyloid plaques: Clumps of protein that damage nerve cell function.

  
  


• 
  

  Tau tangles: Twisted fibers that kill brain cells.

  
  

Over time, brain tissue shrinks, causing severe cognitive impairment.

Key Facts About Alzheimer’s:

• 
  

  It is primarily a brain disorder but can have genetic risk factors, meaning family history can increase chances of developing the disease.

  
  


• 
  

  It is not an eye disease, though vision may be indirectly affected due to brain processing issues.

  
  


• 
  

  It is not a body weight loss disorder, although advanced stages may lead to appetite loss and reduced weight.

  
  

Currently, there is no permanent cure for Alzheimer’s disease, but medications and therapies can slow its progression and improve quality of life.
