Two of the most crucial functions of the human brain are attention and concentration. Any disruptions in them can create a lot of challenges. Mild symptoms of impaired concentration are sometimes seen in the early stages of Alzheimer's disease. It is difficult for them to focus on a task that was never a problem in the past. It hesitates sometimes to abandon the passions you used to find pleasurable. Patients will lose threads during a conversation, a film, or when reading a book. Alzheimer's patients only start to develop more serious literacy disorders a little later. Patients can still read for a long time but lose what they read quickly.
Due to concentration difficulties, patients may also have difficulty making even the simplest decisions. It can also be misidentified as a distraction. Under the right circumstances, even a fit individual finds attention on a task difficult to sustain. But when it happens over and over and starts to bother daily life, it can be a signpost. That is why patients of elderly age should be periodically examined neuropsychologically or submitted for imaging from time to time.
