Early signs of Alzheimer's disease include memory problems, difficulty with spatial orientation, challenges in performing familiar tasks, and learning new skills. These symptoms are common not only in older people but also in middle-aged individuals. So, how does Alzheimer's disease differ from age-related memory decline? Alzheimer's disease differs from age-related memory decline by being more persistent and irreversibly progressive, although its early stages are non-specific. The absence of symptoms unique to Alzheimer's disease in its early stages is the main challenge that hinders early diagnosis. Today, 3 out of 4 patients are diagnosed with the disease at a late stage when 40-50% of the neurons in the brain have already died, leaving limited opportunities to help the patient. Dementia usually involves hallucinations, insomnia, and muscle tone issues, which are absent in Alzheimer's disease. The causes of dementia can be related to vascular pathologies, while Alzheimer's disease is always associated with a hereditary predisposition and neurological changes. Symptoms of Dementia: Confusion; Drowsiness and lethargy; Difficulty concentrating; Memory loss; Prolonged periods of staring into space; Difficulty planning; Disorientation in space; Difficulty using language and numbers. Symptoms of Alzheimer's Disease: Short-term memory impairment; Inattention; Difficulty planning activities; Detachment and apathy—one of the typical signs.
