Study Notes
Neurocognitive Disorders
- Neurocognitive disorders focus on brain functions like memory, processing speed, and problem-solving ability.
- Alzheimer's disease is a distressing neurocognitive disorder.
Cognitive vs. Emotional Disorders
- Cognitive disorders affect brain functions; mood changes can sometimes result, but not directly.
- Emotional disorders, like anxiety and depression, primarily affect feelings and emotional well-being, though they can also affect cognitive functioning.
Delirium
- Delirium is characterized by an acute loss of attention, brain function, concentration, and confusion.
- Delirium usually lasts for a short period (hours or days).
- It's not a disorder itself, but a condition resulting from alack of short-term brain care.
- Potential causes include sunstroke, exposure to fumes, stroke, sleep deprivation, high fever, and even unusual activities like biking in Minnesota.
- Treatment involves addressing the underlying cause of delirium.
Neurocognitive Disorder
- Neurocognitive disorders are categorized into mild and major forms.
- Mild disorders allow functioning with accommodations.
- Major disorders cause substantial impairment in daily activities.
- Deficits arise in cognitive functions like learning, memory, attention, motor skills, decision-making, language, and processing speed.
- Traumatic Brain Injury (TBI), often seen in returning veterans with blast injuries, is an example.
Alzheimer's Disease
- Alzheimer's is the most common type of dementia in the elderly.
- In the US, approximately 6.5 million people are affected by Alzheimer's (and the number is rising).
- Late-onset Alzheimer's (after age 65) is more common, but early-onset (before 65) can also occur.
- Women are diagnosed with Alzheimer's at a higher rate than men.
- The disease involves a slow, gradual loss of brain functions; early stages may resemble delirium.
- Characteristic symptoms include memory loss, difficulties with planning and organization, problems with language (aphasia), impaired motor function (apraxia), and inability to recognize objects (agnosia).
- The disease progresses, eventually leading to changes in personality and overall ability.
- Diagnosing Alzheimer's is usually only possible definitively after death due to physical changes seen in brain tissue.
- Alzheimer's is associated with the presence of plaques and neurofibrillary tangles in the brain; the exact cause is not yet known.
- Excessive activity of specific proteins and genetic links (e.g., ApoE-4 gene) are potential contributing factors.
- Strategies to potentially help with or prevent Alzheimer's include mental and physical activities designed to engage the brain.
Frontotemporal Dementia
- Frontotemporal dementia is a type of dementia resulting from the degeneration of the frontal and temporal lobes of the brain.
- Characteristics include language loss and loss of empathy.
Other Dementias
- Vascular dementia is a type of dementia caused by small strokes throughout the brain's blood vessels.
- Lewy body dementia affects dopamine transmission in the brain.
- Prion's disease, also known as Mad Cow's disease, leads to a rapid loss of function.
Traumatic Brain Injury (TBI)
- Also known as Chronic Traumatic Encephalopathy (CTE), TBI is a result of multiple concussions or blast wave injuries.
Disorders of Cognition and Aging
- Cognitive disorders related to old age are becoming an increasing concern due to an aging population.
- It's important to be aware of cognitive and emotional changes that can accompany old age.
Difficulties in Old Age
- Psychological concerns in old age may arise due to a lack of meaning, feeling unnecessary, loss of life roles, loss of function, sleep problems, and increased occurrences of both physical and psychological illnesses.
- Loss of friends and loved ones is another important factor.
Emotional Problems in Old Age
- Depression and learned helplessness are common emotional issues in older age.
- Substance abuse tends to decrease in older adults.
- Schizophrenia also lessens with age.
Stay Healthy
- Keeping the brain active, engaging in physical exercise, maintaining relationships, and practicing gratitude are beneficial in maintaining cognitive health.
- Getting outside is also a beneficial approach to maintaining both mental and physical health.
Improving Memory
- Current research shows potential non-drug treatments for improving memory and potentially reversing Alzheimer's.
