Study Notes

Risk Factors and Characteristics of Alzheimer's Disease

  • Age is a primary risk factor for developing Alzheimer's disease.
  • The prevalence rate of Alzheimer's disease in the population is not specified.
  • The main characteristic symptom of Alzheimer's disease is cognitive decline.

Neurocognitive Disorders

  • Neurocognitive disorders are a unique category in DSM-5 due to their distinct characteristics.
  • The key factor that differentiates neurocognitive disorders from other psychological disorders is the decline in cognitive abilities.
  • Examples of neurocognitive disorders include Alzheimer's disease, vascular neurocognitive disorder, and traumatic brain injury.

Characteristics of Neurocognitive Disorders

  • Neurocognitive disorders are characterized by decline in cognitive abilities, such as attention, memory, learning, language, and perception.
  • The disorders are typically caused by underlying medical or neurological conditions, such as Alzheimer's disease, vascular disease, or traumatic brain injury.
  • Neurocognitive disorders can result in disability, with 2.5% of the population reporting disability associated with a major traumatic brain injury.

Traumatic Brain Injury

  • Traumatic brain injury is an example of a neurocognitive disorder caused by impact to the head, such as during an automobile accident.
  • Traumatic brain injuries account for approximately 1.4 million emergency room visits annually.
  • The estimated number of hospitalizations due to traumatic brain injuries is approximately 275,000 annually.

Differentiation between Major and Minor Neurocognitive Disorder

  • The main difference between major neurocognitive disorder and minor neurocognitive disorder according to DSM-5 is the severity of cognitive decline.
  • Major neurocognitive disorder involves significant decline in cognitive abilities, while minor neurocognitive disorder involves modest decline.

Physical Damage in Alzheimer's Disease

  • In Alzheimer's disease, physical damage occurs in the brain, characterized by beta-amyloid plaques and neurofibrillary tangles.
  • The progressive nature of Alzheimer's disease leads to increased damage over time.

Early Signs of Alzheimer's Disease

  • Early signs of Alzheimer's disease include memory loss, confusion, and difficulty with communication and problem-solving.
