Alzheimer’s disease: Causes and symptoms

Alzheimer’s is a type of neurodegenerative disease. This is the most common form of dementia. There is no cure for this disease, the disease worsens as it progresses and eventually leads to death.

Alzheimer’s disease is a progressive neurological disorder in which brain cells die. It usually affects people 65 years of age or older. And in some cases seen in younger people. People with Alzheimer’s disease are a little confused at first and start to forget a lot.

As brain cells are affected, the number of neurotransmitters involved in sending messages or signals to brain cells decreases. Levels of the neurotransmitter, acetylcholine, are lower in the brain, especially in people with Alzheimer’s disease.

We will discuss the causes and symptoms of Alzheimer’s disease.

Causes of Alzheimer’s disease

The exact cause of Alzheimer’s disease is not yet known. It is hypothesized, however, that at an early stage brain proteins fail to function normally which disrupts the function of brain cells. Gradually the cells become damaged and lose contact with each other. Eventually, the cells die. Let us discuss it –
