Alzheimer’s Disease- Types, Causes, Symptoms & Treatment

Alzheimer’s Disease- Types, Causes, Symptoms & Treatment

Alzheimer’s is a progressive disease and a type of dementia that affects memory, thinking and behavior. This disorder causes brain cells to degenerate and die.

According to Statista: The most recognized and common type of dementia is Alzheimer’s disease, which accounts for over half of all cases.

Alzheimer’s disease is a decline in the ability to think and understand. Symptoms begin to grow severe enough that they start interfering with daily tasks of the sufferer. The disease can occur in people in their 30s and 40s and is also more commonly seen among older individuals. But it cannot be considered as a part of normal aging.

Types of Alzheimer’s disease

Nearly everyone who struggles with Alzheimer’s disease will eventually face similar symptoms- memory loss, confusion, a problem with decision making and doing daily tasks.

As per the reports, In India, more than 4 million people are estimated to be suffering from Alzheimer’s and other forms of dementia, giving the country the third largest caseload in the world, after China and the US. India’s dementia and Alzheimer’s burden is forecast to reach almost 7.5 million by the end of 2030.

There are two main types of the disease:

  • Early-onset Alzheimer’s

This type occurs to people who are below the age of 65. Generally, they are in their 40s or 50s when they get diagnosed with this type. The early-onset form is also linked with a defect in chromosome 14,  a specific part of the person’s DNA.

  • Late-onset Alzheimer’s

This type is the most common and occurs to people who are 65 years of age or above. The exact cause is not yet identified, but the scientists are working on it.

Another subcategory of the condition is Familial Alzheimer’s disease and is very rare. It is linked to genes and members of at least two generations get affected in such families. This form accounts for only 1% of the total cases of the disease.

Causes of Alzheimer’s disease:

  • Age

The most dominating cause of Alzheimer’s and other dementias is age, but the diseases are not a normal part of aging. People who are 65 years of age or above are at higher risk and this risk doubles every five years.

According to the India Ageing Report 2017, the elderly population, which is growing at a faster rate of three percent, May up the burden of Alzheimer’s in India, as the disease primarily occurs in patients over the age of 60.

There are various researches that are working towards learning how age-related changes affect neurons and other brain cells.

  • Family history

Family history is another strong cause of the disease. A person who has a parent, brother or sister with this disease are more likely to suffer from the disease. People’s genes that they inherit from their biological parents influences the chances of them developing this disease.

  • Health and lifestyle factors

Research advocates that there are many other factors that can cause this disease. Such factors can be prevented from influencing the chances of occurrence.

  1. Head injury

Head injury increases the risk of dementia in future. You can always protect yourself from head injuries by ensuring safety while driving or making floors of your home fall-proof.

  1. Heart disease

There is a strong link between heart health and brain health. The heart pumps blood through the blood vessels that carry blood to the brain. When the person suffers from any heart diseases, then it is likely to cause this disease.

  1. Lifestyle factor

A sedentary lifestyle increases the chances of developing Alzheimer’s disease. An expert neurosurgeon will advocate adapting to a healthier lifestyle to reduce the risk of developing Alzheimer’s and other dementias.
