Have you found yourself feeling forgetful, unfocused, scattered, or confused, especially when making decisions? Often erroneously chalked up to old age and the onset of dementia, according to studies of older adults, forgetfulness, attention lapses, and diminished mental sharpness are more closely related to mood and general health than to age or the risk of Alzheimer’s disease. These conditions may be the side effect of a medication, the result of an underlying medical condition, or most often the result of a sleep or mood disturbance or everyday stress.
