Alzheimer’s is a neurodegenerative disease, mainly characterised by the slow onset of symptoms (such as memory loss, language alterations, spatial and temporal disorientation, etc.), which evolve as the years pass.

It was first described by the German psychiatrist and neurologist Alois Alzheimer in 1906, which is why it is named after him.

It is generally diagnosed in people over the age of 75, although there are a growing number of cases found of early appearance of the disease, so it can be separated into two broad groups: Late-Onset AD and Early-Onset AD.

One peculiarity of Alzheimer’s is that even today, its causes are unknown; this is why research takes special priority at Fundació ACE.
