Deep brain stimulation for dementia

18 Apr

Science Daily has the details:

“Their research has shown that new brain cells, or neurons, can be formed by stimulating the front part of the brain which is involved in memory retention using minute amounts of electricity.
The increase in brain cells reduces anxiety and depression, and promotes improved learning, and boosts overall memory formation and retention.
The research findings open new opportunities for developing novel treatment solutions for patients suffering from memory loss due to dementia-related conditions such as Alzheimer’s and even Parkinson’s disease.”

You can find the original paper here. From the paper:

“Overall, these findings suggest that chronic ventromedial prefrontal cortex high-frequency stimulation may serve as a novel effective therapeutic target for dementia-related disorders.”



“Sleep disturbances may be an early warning sign of Alzheimer’s”

A post from the blog Neurophilosophy:

“The research shows that people with Alzheimer’s, Parkinson’s and several other neurodegenerative conditions often experience sleep disturbances many decades before any symptoms appear, and that these disturbances are somehow linked to disruptions of the circadian rhythm. They include common sleeping difficulties such as insomnia, sleep apnoea, and daytime drowsiness, and some slightly more unusual ones. According to one small study published in 2011, for example, the early stages of Parkinson’s disease are characterised by alterations in the content of dreams, particularly the presence of animals and increased aggressiveness.”

Here is Dr. Greger on optimal sleep duration:
