Description of Alzheimer’s disease

DefinitionAccording to dictionary definition  With old age, there is a decline in mental and physical functions. Some older people forget names, misplace things from time to time, which is a normal part of aging. But, when this starts affecting the daily life of the person, it leads to €œdementia. €Dementia is a condition in which there is a loss of memory, confusion, difficulty in problem-solving or judgment of a person.
One of the most common causes of dementia is Alzheimer €™s disease (AD). This is a disease of the brain which gradually begins after the age of 60 years but worsens  soon over a period. This disease leads  to the death of a large number of nerve cells in the brain.  Causes

In AD, there is a failure of functioning of nerve cells in the brain. This is due  to abnormal material (protein) accumulation in the brain which disturbs the communication between brain cells and leads to shrinkage and death of the brain cells. But, why this happens is still unknown.  Risk factors

1. Age: People aged 65 years and above are more prone.2. Family history: Studies have shown that people whose siblings, parents, or relative had Alzheimer’s disease are more likely to develop it.3. Genetic: Studies have shown that people who inherit genes like APOE-e4, APOE-e2, and APOE-e3 may have a risk of developing AD.  4. Other diseases: People with heart disease, diabetes, stroke, high blood pressure, and high cholesterol have a higher risk of developing AD.5. Head injury: Strong association of developing AD, if a person has had a serious head injury at some point in his life.  Signs and SymptomsAccording to dictionary definition  
Some people with initial stage of AD have only mild memory loss and can carry out their day to day activities. This is known as mild cognitive impairment.
As the disease progresses, the person may show early and then late signs.

History and examination: Doctor would ask the patient and the family members staying with the patient about the general health, medical history, history of head injury, family history, and recent changes in memory, behavior and personality.2. Simple tests: Memory test, simple problem solving test, and counting3.
