Multiple Sclerosis Linked to Vitamin D Levels, Study Says

People with high levels of vitamin D in their blood have shown a lower risk of developing multiple sclerosis, according to results of a Swedish study released Monday.  The new study adds to a growing body of research suggesting a link between vitamin D and MS, an autoimmune disease that affects the brain and spinal cord that is believed to afflict more than a quarter-million Americans.

The Case for Drinking as Much Coffee as You Like

"What I tell patients is, if you like coffee, go ahead and drink as much as you want and can," says Dr. Peter Martin, director of the Institute for Coffee Studies at Vanderbilt University. He's even developed a metric for monitoring your dosage: If you are having trouble sleeping, cut back on your last cup of the day.

Anti-depressants could help stroke patients recover more quickly by 'rebuilding' the brain

'The results of this meta-analysis are extremely promising. We do not yet fully understand how anti-depressants could boost recovery after stroke, but it may be because they promote the growth of new nerve cells in the brain, or protect cells damaged by stroke.' ….by preventing depression, the drugs may help patients to be more physically active which is known to aid overall recovery.

'We now need to carry out a number of much larger clinical trials in order to establish exactly if, how and to what extent antidepressants can help stroke survivors recover.'
