ALZHEIMER

Dementia is a progressive, chronic brain disease that impairs the ability to carry out daily living activities.

Dementia involves a general deterioration of higher cortical functions without affecting the individual's awareness (consciousness). These functions include memory, the ability to cope with daily demands, perception and motor skills, social behavior, and emotional control. Most cases are irreversible and progressive.

Alzheimer's Disease (AD) is one of the most common forms of dementia and is becoming increasingly prevalent in industrialized countries as the population ages. Alzheimer's Disease usually progresses very slowly, and many cases present a preclinical stage characterized by memory problems. While the incidence of Alzheimer's increases with age, it can also affect younger individuals in their fifties, so it should not be considered solely a disease of the elderly.

Types of Alzheimer's Disease

There are two main types of Alzheimer's Disease:

Familial Alzheimer's Disease: This is quite rare. Experts have different opinions on its prevalence; some say it accounts for 5% of all Alzheimer's cases, while others suggest it is only 1%. The hereditary nature of this type has been proven, though it does not play a role in all cases. Younger patients in their fifties are typically included in this group.

Sporadic Alzheimer's Disease: This accounts for 95% of all cases and is the typical form seen in older adults.

Having a family member with Alzheimer's does not mean that you will also develop the disease or pass it on to your children.

Causes of Alzheimer's Disease

The exact cause of Alzheimer's Disease is unknown, and various potential factors are being discussed. A combination of these factors may contribute to the onset of the disease.

Brain Dysfunction in Alzheimer's Disease

The brain dysfunction associated with Alzheimer's Disease is characterized by two main processes:

a. The formation of substances that damage neurons (nerve cells);

b. A decrease in the production of neurotransmitters, which facilitate communication between neurons, leading to a disruption in "communication" between neurons.

Understanding these fundamental mechanisms can help in the development of effective interventions and treatments. Early diagnosis and management are critical in improving the quality of life for those affected by Alzheimer's Disease.

By addressing the key aspects of dementia and Alzheimer's Disease, this aims to provide valuable information to those seeking a better understanding of these conditions. Early awareness and intervention are critical in managing the progression of Alzheimer's and improving patient outcomes.
