Study Notes
- Non-neuronal brain cells, including glial cells, meninges, vasculature, and the skull, are the only types of brain cells that can become cancerous.
- Cancer treatment methods include surgery, chemotherapy, radiation, and immunotherapy.
- Chemotherapy drugs are taken up by more active cells, such as those in the hair, nails, skin, digestive tract, and tumors.
- Tumors are highly energy-hungry cells that can grow new blood vessels to supply themselves with more blood.
- Radiation therapy uses beams of hot gamma rays to kill cancer cells by heat.
- Immunotherapy boosts the natural immune system and teaches the body to attack cancer cells.
- Aging weakens the immune system, making it less effective at fighting pathogens and abnormal cells.
- BCG is an immune system stimulant used in immunotherapy to boost the immune system and kill abnormal cells, including cancer cells.
- Seizures are caused by an imbalance between glutamate and GABA, likely due to both too little inhibition and too much excitation.
- Seizures involve the loss of consciousness, slumping over, and convulsions, which are caused by waves of electrical impulses hitting the motor cortex.
- Seizures may be caused by external factors such as brain injuries, high fevers, and oxygen deprivation.
- Epilepsy is a recurring condition characterized by two or more untriggered seizures.
- Seizure first aid involves protecting the head, laying the person on their side, and calling 911.
- Seizure disorders are treated by reducing excitation or increasing inhibition through drugs, and some seizure drugs are also effective against bipolar disorder.
