Leukenzephalopathien can be due to many reasons: infections, hereditary diseases, Multiple sclerosis, Heroin, cocaine, or cancer therapy can also drag the white matter affected. Now the woman take neither drugs nor medicines, wrote William Rae and colleagues on the case in the medical journal JAMA Neurology, but food supplements in high doses: “you were on your own over-the-counter selenium supplements to take”, so the Doctors – in order to strengthen your immune system. A year ago, she started with a 200-microgram tablet per day is already significantly above the recommended daily dose. Half a year ago, you had then increased to at least six to eight pills daily. “When she came to us, was her selenium level in the blood serum is extremely high: 5370 micrograms per Liter,” wrote Rae and colleagues.

For patients with intestinal or kidney disease supplements can be useful under medical supervision. Because selenium is easily overdosed. Medicinal products with more than 70 micrograms per day are, therefore, only on prescription. A dietary Supplement but it does contain 200 micrograms (although the Federal Institute for risk assessment maximum of 45 is recommended). So stay away from bad Boys: 300 microgram, just one and a half Pillchen a daily basis, threatening of acute symptoms of an Overdose.
