Most perinatal strokes lead to neurologic disorders

Researchers found that cerebral palsy was more likely to occur in infants who had no symptoms early in life and sustained injury to deep structures of the brain. The study included over 199,000 children born between 1997 and 2002 and reported a higher rate of significant long-term neurologic impairment.

Animal model demonstrates course of epilepsy

Researchers created rat pups with subtle cortical malformations and found that they developed temporal lobe epilepsy after experiencing prolonged fever-related seizures. The study suggests that early identification of children with atypical febrile seizures could lead to neuroprotective treatments to prevent later epilepsy.

Epilepsy by the numbers

Researchers have developed a mathematical way to translate brain wave readings into simple terms to help doctors identify newborns at risk for epilepsy. The new tool uses quantitative EEG analysis to pinpoint abnormal brain activity in real-time.

Pregnant women with epilepsy face dilemma

Women with active epilepsy can have a healthy child if they continue treatment, but the risk of birth defects varies depending on the medication. The importance of individualized counseling and maintaining seizure control is emphasized to balance treatment effectiveness and potential risks.

Breakthrough for kids with epilepsy

Researchers found that children aged 3-7 years old who underwent epilepsy surgery experienced significant improvements in development, with 82% showing stable gains and three children gaining over 15 points in IQ. Seizure-free outcomes were linked to better cognitive function 2-3 years post-surgery.

Carnegie Mellon and U. of Pittsburgh create tool to understand neuron rhythms, learning

Researchers at Carnegie Mellon and University of Pittsburgh have created a new method to calculate the phase-resetting curve (PRC) of living neurons, which can help elucidate mechanisms for neural synchrony and study learning. The tool combines computational and experimental approaches to simplify complex dynamics of single neurons.

Researchers model brain's electrical storm during a seizure

UC Berkeley researchers developed a mathematical model of the brain's electrical activity during seizures, which may aid in understanding and treating epilepsy. The model, compared with real-world data from electrodes implanted in a patient, suggests that strong coherent waves of electrical activity are responsible for seizure spread.

Drivers with epilepsy are on the road again

A new driving regulation in Japan allows people with epilepsy to obtain a driver's license after a seizure-free period of two years. The survey results highlighted the need for cooperation between authorities and the Japanese Epilepsy Society to further amend regulations and educate the public, patients, and professionals.

Tip sheet for the October 26, 2004 Neurology

Researchers found that switching from brand phenytoin to generic phenytoin can lead to increased seizures in epilepsy patients. Additionally, a study on concussion history and symptom reporting found that athletes with previous concussions reported fewer symptoms immediately after the injury but more symptoms one week later.

Epilepsy study shows memory loss after brain surgery

A recent study published in Epilepsia found that selective amygdalohippocampectomy (SAH) surgery can lead to verbal memory loss in patients, especially those who underwent left temporal lobe surgery. The study revealed that 30% to 50% of patients who underwent SAH on the left side showed no recovery of verbal memory after 12 months.

Brain has center for detecting sound motion

Researchers identified a brain region that processes sound location and motion, with impaired function leading to 'cortical motion deafness'. The study provides evidence of an auditory motion module within the right posterior superior temporal gyrus.

Convulsions in worms mimic epileptic seizures

A team of researchers led by Guy A. Caldwell found that worms with a mutated LIS1 gene experience convulsions similar to those in humans with lissencephaly, a rare birth defect. The study reveals the mutated protein's impact on neuronal trafficking and neurotransmitter release, providing insights into the complexities of epilepsy.

Epilepsy drugs cause bone loss

A study of 6,044 women aged 65 and older found that those taking epilepsy drugs lost bone mass at nearly twice the rate of non-users. This increases the risk of hip fractures by 29% over five years. Researchers recommend screening for osteoporosis and counseling on calcium and vitamin D supplements.

Loss of circadian genes results in epilepsy

Scientists discovered that deleting three circadian genes in mice results in severe epilepsy and accelerated aging. The mice lacking all three genes are prone to epileptic seizures and display early mortality, with a significant increase in deaths on Mondays and Thursdays due to sound-induced attacks.
