NUR 290 Lecture Notes - Lecture 26: Traumatic Brain Injury, Generalised Epilepsy, Meningitis
Document Summary
Seizures occur when abnormal electrical signals are being rapidly fired for neurons in the brain. This can happen throughout the brain affecting both sides (generalized seizure) or being located in a specific area of the brain (partial or focal seizure). Seizures can occur in anyone (children and adults) due to a severe acute condition, such as a high fever, illness (especially central nervous system types like bacterial meningitis), hypoglycemia, acid-base imbalances like acidosis, alcohol withdraw, brain tumor etc. Once the condition is corrected the seizures tend to stop. Epilepsy is where the patient has frequent seizures due to a chronic condition of some type like congenital brain defect, stroke, traumatic brain injury, long-lasting effects of an infection etc. In the brain, our neurons are tasked with handling and transmitting information. There are two types of neurons i want to discuss. Just like their name says, excitatory neurons produce an action or cause.
