Neurodegenerative Disorders

  • Alzheimer's disease: A progressive brain disorder that causes memory loss, confusion, and eventually death.
  • Parkinson's disease: A progressive brain disorder that causes tremors, rigidity, and difficulty with movement.
  • Amyotrophic lateral sclerosis (ALS): A progressive brain disorder that causes muscle weakness and paralysis.
  • Huntington's disease: A progressive brain disorder that causes involuntary movements, cognitive decline, and psychiatric symptoms.

Mental Disorders

Causes And Risk Factors

Government Health Most Common

The causes of brain disorders are not always known, but there are a number of factors that can increase the risk of developing a brain disorder, including:

  • Genetic factors: Some brain disorders are caused by genetic mutations.
  • Environmental factors: Exposure to certain environmental toxins, such as lead and mercury, can increase the risk of developing a brain disorder.
  • Lifestyle factors: Certain lifestyle factors, such as smoking, excessive alcohol consumption, and lack of exercise, can also increase the risk of developing a brain disorder.

  • Neurological examination: Your doctor will test your reflexes, coordination, and other neurological functions.
  • Imaging tests: Imaging tests, such as MRI and CT scans, can help your doctor see the structure of your brain and identify any abnormalities.
  • Laboratory tests: Laboratory tests can help your doctor identify any underlying medical conditions that may be causing your symptoms.

Treatment Of Brain Disorders
