Study Notes

Brain Disorders and Functions

  • Korsakoff's syndrome is primarily caused by a lack of thiamine (Vitamin B1) in the body.
  • In Chronic Traumatic Encephalopathy (CTE) sufferers, the brain's frontal and temporal lobes are highly affected.
  • The main characteristic symptom of Multiple Sclerosis (M.S) is the demyelination of neuron axons, disrupting communication between brain cells.
  • The myelin sheath's function in the brain is to facilitate the rapid transmission of electrical signals along neuron axons.
  • Neurons are the most energy-hungry cells in the brain and die first in the event of energy deprivation.
  • Destruction of the mammillary bodies through thiamine deficiency leads to Korsakoff's syndrome, a severe memory disorder.
  • Korsakoff's syndrome can be caused by a combination of factors, including chronic alcohol abuse, poor nutrition, and severe illness.
  • Multiple Sclerosis (M.S) is typically treated with a combination of medications, rehabilitation, and lifestyle changes to manage symptoms and slow disease progression.
