Stanford researchers using functional MRI have discovered changes in those highly hynotizable while undergoing hypnosis. First, a decrease in brain activity was seen in brain's salience network (dorsal anterior cingulate). Second, an increase in brain connections that help the brain process and control activity in our bodies (connections between dorsolateral prefrontal cortex and the insula). Lastly, reduced connections between the dorsolateral prefrontal cortex and the default mode network (medial prefrontal cortex and the posterior cingulate cortex).
This study offers evidence that hypnosis is more than a swinging pocket watch it is a powerful means of changing the way we use our minds to control our body and our perceptions. One example: pain control.

Pregnant Moms Take Your Ditamin D to Protect Your Baby Against MS
According to a Danish registry study higher levels of vitamin D in newborns was associated with less risk of developing multiple sclerosis decades later.

Comparable findings were reported in a Finnish registry measuring the mother's serum vitamin D level.

Disrupted Sleep Increases Risk of Atrial Fibrillation
Researchers at UCSF after examining three sources of data have concluded that disruptions in sleep may increase the risk of developing atrial fibrillation later in life.
People with frequent nighttime awakening had a 26% increase risk of developing atrial fibrillation. People with insomnia had a 29% increased risk of developing atrial fibrillation.
Why disturbed sleep is associated with the development of atrial fibrillation is unknown. It may be hypothesized that disturbed sleep negatively impacts the autonomic nervous system.
Poor sleep is associated with other risk factors for heart disease including stroke, high blood pressure and obesity.
Improved sleep hygiene may help prevent atrial fibrillation and its associated risk of stroke.

High Blood Pressure ? Blame it on Your Childhood
Children with a history of childhood mistreatment, poverty or family dysfunction may have poor blood pressure regulation. Blood pressure variability has been linked to numerous problems in adults including increased risk of stroke, poor post-stroke recovery and decreased brain function in the elderly.
AHA Meeting Report Presentation: 307 Session : EP.AOS.760
Previous research has found an association between adverse childhood experiences and a more rapid increase of blood pressure in adulthood. Further, early-onset hypertension and prehypertension have been linked to preclinical heart disease such as increased arterial stiffness and left ventricular hypertrophy.

THROW OUT YOUR "PURPLE PILLS" : Proton Pump Inhibitors Possibly Increase Stroke Risk
PPI's (omeprazole, pantoprazole, lansoprazole, esomeprazole) have been found to be associated with vascular dysfunction including kidney disease, heart attacks and dementia. A recent American Heart Association presentation indicates that a review of records of 244,679 Danish patients with nearly a six year follow up revealed a 21% overall increased risk of ischemic stroke in those taking PPI's. The greatest risk was found with pantoprazole (94%).
A similar risk was not found in those that took H2 blockers (famotidine, ranitidine).

Hope for Alzheimer's Patients and Their Families ?
As reported by Researchers Against Alzheimer's (RA2) there are 57 drugs in mid-stage testing (phase II) and 23 drugs in late-stage testing (phase III). These drugs could prevent or delay the symptoms of dementia. Phase II/III treatments include AC-1204, an oral drug for patients with mild to moderate Alzheimer's whose mechanism of action is to improve mitochondrial metabolism through chronic ketosis. Also, a combination of albumin and immunoglobulin administered IV with possible anti-amyloid antibodies and albumin binding capacity is in mid/late stage development to treat mild to moderate Alzheimer's disease.

Factors Identified as Increased Risk of ALS at an Earlier Age
People with a BMI (body mass index) above the highest 1/3 percentile (greater than or equal to 25) have a higher risk of developing ALS at a younger age. People with an IQ above the highest 1/3 percentile have a significantly higher risk of developing ALS at an age of 56 and older. People with physical fitness above the highest 1/3 percentile have a higher risk of developing ALS before age 45.

Treat Hypertension Mid-life to Preserve Late-life Brain Function
According to a review of the literature by a panel of experts, treatment of hypertension in mid-life preserves late-life cognitive function.
Hypertension disrupts the function and structure of cerebral blood vessels which leads to ischemic damage (as a result of decreased blood flow to brain cell's) of white matter regions critical for cognitive function and may promote Alzheimer pathology.
Hypertension Oct 10 2016
As previously reported, treatment of elevated blood pressure in the oldest of the old should be more conservative than treatment of younger patients.
