Alzheimer's is cause of dementia which predominantly affects the memory. It may come with age and may interfere with your day to day life or your normal functioning. In this disorder, the brain cells start to degenerate and die. Alzheimer's disease is known as the commonest cause of dementia, where there is a loss of thinking and social skills, that can disturb a person's everyday functioning. It predominantly affects brain's every function, like your behaviour, intellect, how you dress , how you carry on your professional duties, etc.

Alzheimer’s disease is one of the most difficult and emotionally challenging diseases to experience for a person and their loved ones. World Alzheimer’s Day is celebrated every year around the world to raise awareness about this disease and to support those who suffer from it.

On this occasion, Onlymyhealth editorial team talked to Dr. Rajiv Anand, Senior Director, Neurology, BLK Super Speciality Hospital, Delhi, mainly about the stages, symptoms, risk factors and treatment for Alzheimer's disease.

Stages of Alzheimer's disease

Dr. Rajiv said, "In Alzheimer's, the memory starts getting affected to the point that you are forgetting the routine things and are not being able to carry out your routine work. The person even tends to repeat a thing too often. This is medically called Palilalia. This happens because they want to tell their brain again and again but it takes longer to respond. According to Dr. Rajiv, here are the stages of Alzheimer's disease:

1. Early stage

In the earlier stages, it is a memory problem but the patient can do easy tasks of daily living for themselves. They can fulfil basic needs like bathing themselves, eating on their own, etc. One feature of memory failure is when people are unable to name things. For example, if he/she has fruits kept in front, then they won't be able to name that fruit or won't be able to name familiar faces. So, this is what happens in the earlier stage. It is advised that a dementia patient should have a tattoo of their contact number or address, which can help incase they are found wandering.

2. Moderate stage

Brain functions manage a person's movement and conduct in social situations too. And this involves the usage of your memory. In this moderate stage, the patient suffering from Alzheimer's disease won't be able to do professional works and will also not be able to take self care. They become totally dependent on their family and friends in this situation. They become helpless and cannot do ADL (activities of daily living), so the daily living relies on the care givers then.

3. Final stage

The third and final stage would be that they lose their whole identity and become bed ridden. They are dependent for everything now. When the normal brain stops functioning, there are many abnormal things that come up. Suppose, if a person gets agitated, he/she may start hallucinating or start seeing things that aren't there. Then the normal brain function gets disrupted, which becomes worrisome for the care givers and for the society.  abnormal sexual advances to people. In this end stage, the patient lies curled up in the bed in the fetal posture. And the situation only gradually worsens. The patient becomes unaware of what is happening to him. In fact, they might even take off their clothes or pass urine at any place.
