Description
recurrent seizures
- anatomy
- definition of seizure
- A sudden, uncontrolled electrical
disturbance in the brain, causing
changes in: behavior, movements, or
feelings & in levels of consciousness.
- Due to an abnormal, excessive, hypersynchronous discharge of a
population of cortical neurons. (30 seconds to 2 minutes)
- pathology

- Epilepsy
- A disorder characterized by
- 1)recurrent seizures 2)unprovoked
by an acute insult.

- Seizures vs Epilepsy
- What causes a seizure?
- decrease in inhibitory NT OR increase excitatory NT or its receptors
- causes in children
- causes in both
- metabolic disorders causing seizures
- pharmacological treatment
- causes in children
- decrease in inhibitory NT OR increase excitatory NT or its receptors
- A disorder characterized by
- Convulsions
- An abnormal, sudden, violent, involuntary contraction of the
muscles most typically seen during seizures
- Also, not all convulsions are due to seizures.

- Phases of a seizure
- Aura stage
- Ictus Stage
- Postictal Stage
- Postictal Stage
- Ictus Stage
- continuous seizures occurring for longer than 30 minutes.
- Aura stage
- A sudden, uncontrolled electrical
disturbance in the brain, causing
changes in: behavior, movements, or
feelings & in levels of consciousness.
- epidemiology
- Approximately 50 million people currently live with epilepsy worldwide. The
estimated proportion of the general population with active epilepsy (i.e. continuing
seizures or with the need for treatment) at a given time is between 4 and 10 per 1000
people. However, some studies in low- and middle-income countries suggest that the
proportion is much higher, between 7 and 14 per 1000 people.
- Globally, an estimated 2.4 million people are diagnosed with epilepsy each year. In
high-income countries, annual new cases are between 30 and 50 per 100 000 people in the
general population. In low- and middle-income countries, this figure can be up to two times
higher.
