Alzheimer’s disease, also referred to as senile dementia, is a progressive, chronic neurodegenerative disorder which causes brain cells or neurons to degenerate and undergo a mechanism of programmed cell death which is different from classical apoptosis. It is the most common cause of dementia and accounts to 60-80% of the cases. Dementia is characterised by a decline is memory and loss of other cognitive abilities like language, problem solving and thinking skills and can have a negative impact on the daily life of the patient. Another common early symptom of Alzheimer’s in amnesia. Other symptoms may involve reduced ability to register new information, decline in reasoning, complex and multi tasking, and decision making capabilities. The greatest known risk factor is increasing age with majority of the patients being 65 years or age and older. It is caused when beta-amyloid protein accumulates and disrupts cell to cell communication, causes inflammation and eventually may kill off brain cells. However, Alzheimer’s is not just restricted to old age. Millions of cases worldwide report the Alzheimer’s patients being under the age of 65. This is known as Early-onset Alzheimer’s. In the initial stages, the memory loss is mild but as time progresses the memory loss worsens and individuals might even lose the simple abilities to carry on a conversation or respond to stimuli. Post diagnosis, a patient generally lives for somewhere between 4-8 years but can also live for as long as 20 years. Alzheimer’s Disease has no known cure. However, treatments are available for the symptoms which may temporarily decelerate the worsening of the disease but the treatments can’t stop Alzheimer’s from progressing.

Therefore, doctors may observe signs and symptoms, the patient’s medical history and carry out assessments like blood or urine tests, CT (computed tomography) scan or MRI (magnetic resonance imaging) scan of the brain. Sometimes the symptoms might be related to inherited disorders like Huntington’s disease. Therefore, genetic testing may be done while recording family history.

After this, the diagnostician may eliminate other conditions and take an assessment of cognitive abilities and perform genetic testing.


Basic questions about age, family relations, names, times or numbers or location might be asked.

There is no known cure for Alzheimer’s disease. The death of brain cells cannot be reversed. However, treatments are available for the symptoms which may temporarily decelerate the worsening of the disease but the treatments can’t stop Alzheimer’s from progressing.

These treatments might involve drug therapy with cholinesterase inhibitors like

  • Donepezil
  • Rivastigmine
