Why seizures occur with alcohol withdrawalEpileptic seizures are the most dramatic and prominent aspect of the "alcohol withdrawal syndrome" that occurs when a person abruptly stops a long-term or chronic drinking habit. Scientists have shown that the flow of calcium ions into brain cells via voltage-gated calcium channels plays an important role in the generation of alcohol withdrawal seizures, because blocking this flow suppresses these seizures. But do the changes in calcium........Go to the Neurology news blog (Added on 10/19/2009 7:12:46 AM)
