Alzheimer's is a progressive and irreversible disease. It is characterized by the slow onset of symptoms that evolve over time: memory loss, changes in character and behaviour, as well as problems in language and orientation.

In general, it is diagnosed in people older than 75 years, although more and more cases of early onset are detected.

This disease was first described in 1906 by the German psychiatrist and neurologist Alois Alzheimer, and so it was named after him. One of its peculiarities is that, still today, its causes are unknown and, for this reason, research becomes key.
