The lifetime risk of stroke for men and women over age 25 globally is 25%.
In an NEJM study, large geographic variations were found. In 2016, the highest-risk regions were East Asia (38.8%), Central Europe (37.1%), and Eastern Europe (31.6%). The lowest region of stroke risk was sub-Saharan Africa (11.8%).

UH OH: A History of Drug Treatment for ADHD dramatically Increase Risk of Parkinson's Disease
From a report from the Center for Disease Control and Prevention 3/4 of children with ADHD are prescribed amphetamine or methylphenidate. A study from the U of Utah school of Dentistry provides provocative findings. Individuals with ADHD are 2-3 times more likely to develop Parkinson's disease than those without.
Further, those with ADHD who were prescribed psychostimulant drugs were 8 to 9 times more likely to develop Parkinson's.

Bullying Hurts the Brain !
Investigators at King's College London in their IMAGEN project found that bullying was associated with decreases in the volume of particular brain structures namely the caudate and putamen. These structural changes could increase the likelihood of mental illness such as higher levels of generalized anxiety identified in their study population by age 19.

African Folk Remedy's for Seizures Molecular Mechanism discovered
The leaf extract from the shrub Malotus oppositifolius helps to control seizures. Now researchers at UC Irvine have identified two components from the leaf extract activate KCNQ2/3, a potassium channel essential for controlling electrical activity in the brain. These two components together are highly effective at activating these potassium ion channels and preventing seizures.
Isovaleric acid, a component of valerian root is one of these active compounds in this African folk remedy.
Amazing.

From the Framingham heart study, researchers found that middle-aged individuals with high levels of cortisol in their blood have impaired memory compared to those with normal cortisol.
Hmm...stay tuned.
