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.
The American Academy of Neurology has released a guideline evaluating the treatment of infantile spasms, a severe form of epilepsy. The guideline recommends adrenocorticotropic hormone (ACTH) as a short-term treatment option, but notes that there is insufficient evidence to recommend optimum dosage and length of treatment.

The process eliminates ethical and logistical issues associated with fetal tissue use and allows for quick conversion within a few weeks.
A recent study by American Academy of Neurology found that patients taking pergolide for Parkinson's disease have a higher risk of developing valvular heart disease. Eighty-nine percent of pergolide-treated patients showed some degree of valvular insufficiency, with increased risks in the mitral and aortic valves.
A recent study found that men who served in the military were 60% more likely to develop ALS than men who did not serve.

Surgery for medically intractable temporal lobe epilepsy shows variation among ethnic groups, with African Americans receiving surgery at significantly lower rates than non-Hispanic whites. The study suggests that racial disparities exist but do not appear to be related to differences in access to care.
A new study found that infusing a molecule called glial cell line-derived neurotrophic factor (GDNF) directly into the brain improved Parkinson's disease symptoms in 41% of patients. The GDNF infusion resulted in significant increases in dopamine production and was sustained for at least two years, according to the research.

Researchers found that a widely used reading test, the National Adult Reading Test (NART), can accurately predict an individual's pre-dementia cognitive abilities. The study compared NART scores with IQ scores from childhood and showed no significant difference between demented and non-demented individuals in terms of NART scores.
A new AAN guideline has resolved debate surrounding the role of Patent Foramen Ovale (PFO) in stroke risk. The guideline found no evidence to support or refute closing PFOs, but notes an increased risk for younger patients with both a PFO and atrial septal aneurysm (ASA). Further research is needed to determine the best treatment options.

A study of 1,036 individuals from 266 families discovered that genetics significantly impacts memory performance, accounting for up to 80% of the variation. The influence of genes on memory abilities was stronger than previously thought and appears to be relatively unaffected by the presence of Alzheimer's disease.
A clinical trial found that low-dose clozapine can reduce levodopa-induced dyskinesias (LIDs) in people with severe Parkinson's disease by around 50 percent. The study suggests that clozapine may mitigate the transmission of toxically high levels of levodopa, thereby reducing its potency and lessening the severity and duration of LIDs.
Researchers found that free testosterone was associated with a decreased risk of Alzheimer's disease in men. A Netherlands study also linked higher consumption of fatty fish to reduced impaired cognitive function and speed. In contrast, higher dietary cholesterol intake was associated with increased risk of impaired memory and flexibil...
A study found that women taking high doses of vitamin D supplements were 40% less likely to develop multiple sclerosis. Vitamin D levels in the blood prior to onset of MS should be measured in future studies.
