Alzheimer’s disease (AD), is a neurodegenerative disease, which occurs due to the death of brain cells or neurons. In fact, Alzheimer’s disease is a kind of dementia, that affects memory, thinking, and behaviour. It’s symptoms starts slowly but gets progressively worse with time. Alzheimer’s disease is generally refers as Alzheimer’s. About 60 – 80 % cases of dementia are of Alzheimer’s only. People suffering from dementia experience forgetfulness or difficulty in remembering recent events. As it’s progress, the symptoms gets so worsen that patients can’t even recognize his/her loved ones. It is to be clear that there is no permanent cure or treatment of Alzheimer’s, which can cure this disease completely. But yes, treatment can slow down the affects and progression of this disease.

Stages of dementia:  There are seven stages of Alzheimer’s disease —

  • Stage 1 – There are no noticeable symptoms at this stage, but one can be diagnoses if he or she has any family history of Alzheimer’s.
  • Stage 2 – There is a beginning of the symptoms of Alzheimer’s. TThe earliest symptom one can notice is forgetfulness.
  • Stage 3 – In this stage, mild physical and mental impairment occurs. Any person very close to the patient may notice these symptoms.
  • Stage 4 – Alzheimer’s disease can be diagnosed at this stage, because of the noticeable effects on the patient. In this stage, the patient suffers mild memory loss and the inability to perform everyday tasks.
  • Stage 5 – In this stage, a patient needs the help of his or her family’s assistance to perform everyday tasks. Moderate to severe symptoms can be observed.
  • Stage 6 –  When patients is unable to perform basic tasks such as eating, getting ready etc. Then we can consider the patient at the sixth stage of Alzheimer’s.
  • Stage 7 – Loss of speech and facial expressions, feeling unable to recognise his/ her family members are the symptoms of final stage, with many other severe symptoms.

As the stages progress, patients needs more attention and support of their family, friends and caregivers.

It’s symptoms are mild memory loss, difficulty in performing everyday tasks, poor concentration and even sometimes mild poor vision, etc.

Causes of Alzheimer’s:  The cause of most of the Alzheimer’s cases are still unknown. When the brain proteins fails to work normally, it disrupts the working of brain cells called neurons. This condition triggers a series of toxic events and damage the brain cells. Damaged neurons lose connections to each others and die at last.

Only 1 – 3 % cases have some known or familiar causes like —
