“It is characterized by gradually and progressively producing the loss and death of neurons, which leads to the deterioration of cognitive functions, altering functional capacity and producing great disability and dependence,” andexplains in a statement Dr. Juan Fortea, Coordinator of the Behavior and Dementia Study Group of the Spanish Society of Neurology (SEN).

Leading cause of disability in old age

The specific and detailed cause of the disease is unknown. but everything seems to indicate that it has a multifactorial origin. “Different processes are involved, such as the accumulation of certain brain proteins, neuroinflammation, immunity, vascular or genetic changes, which predispose certain people to develop it,” they add in the SEN.

The disease evolves in a predictable way, but it is completely different in each person, depending on multiple factors, such as genetics, life habits or the age of the affected person.

In fact, it may seem “normal” for an older person to experience memory problems over the years. “But this is a misconception that only helps Alzheimer’s disease is underdiagnosedwarns the expert.
