Which Clot-Busting Drug Is Tied to Better Recovery After Stroke?

American Academy of Neurology (AAN) — Wed, 16 Oct 2024 16:00:00 EST

For people with ischemic stroke, treatment with the clot-busting drug tenecteplase is associated with a slightly higher likelihood of an excellent recovery and reduced disability three months later than the drug alteplase, according to a meta-analysis published in the October 16, 2024, online issue of Neurology(r), the medical journal of the American Academy of Neurology. Researchers found that the likelihood of good recovery was similar between the two treatments.

Brain Imaging of Neuromelanin May be Key to Understanding Extensive Substance Use

Stony Brook University — Wed, 16 Oct 2024 13:00:47 EST

A study that used a specialized type of magnetic resonance imaging (MRI), named neuromelanin-sensitive MRI, showed that this type of MRI signal was increased in regions of the midbrain in young adults ages 20 to 24 who had an extensive alcohol and drug use history. The findings are published early online in the American Journal of Psychiatry.

Challenging Current Understanding, Study Reveals Rapid Release of Dopamine Not Needed for Initiating Movement

Harvard Medical School — Wed, 16 Oct 2024 11:00:00 EST

At a glance: Study in mice reveals rapid release of dopamine is not needed for initiating movement but is important for activities related to reward-seeking and motivation. The findings help explain why the widely used Parkinson's drug levodopa improves movement-related symptoms but often fails to ameliorate some cognitive ones. The work may inform the development of new therapies that restore both slow and fast dopamine action to treat multiple symptoms.
