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.
