Alzheimer’s Disease and Other Dementias

Dementia disorders can be classi›ed as cortical, subcortical, progressive, primary, or secondary (National Institute of Neurological Disorders and Stroke, 2007). Cortical dementia is marked by damage to the cortex (the outer layer) of the brain and results in memory impairment, communication problems (including aphasia, the inability to understand or produce speech), cognitive dif›culties (including an inability to recall words), and interpersonal behavior problems (Cleveland Clinic, 2007; National Institute of Neurological Disorders and Stroke, 2007). Subcortical dementia is the result of damage to the brain beneath the cortex (hence, subcortical) and tends to result in memory, movement, and emotional changes (National Institute of Neurological Disorders and Stroke, 2007), as well as personality and attention-span changes (Cleveland Clinic, 2007). Progressive dementia is a dementia that results in greater impairment over time (National Institute of Neurological Disorders and Stroke, 2007).
