Autism
and Schizophrenia in elderly and younger people may have common link because
the levels of vitamin B12 are low in both cases. Researchers have found it.
The
main cause is vitamin B12 levels decrease in brain in older age. The different
levels of vitamin between B12 in blood and brain may imply numerous kinds of
neurological decrease such as old-age dementia, schizophrenia, and disorders of
autism. The scientists have said. Fox News reported it on Feb 15, 2016.
The
study report was published in the Journal PLOS ONE in January, 2016. The study
supported an emerging theory that our brain uses vitamin B12 in a strictly
regulated system to promote neurological development and to control gene
expression from the periods of fetal development and early childhood, in
adolescence and then in middle and old age.
Vitamin
B12 which is also called cobalamin has a vital role in the formation of blood
and the normal function of our nervous system. The sources of B12 are animals,
though it is also found in some plant-based foods.
In
the study, scientists examined at least 60 deceased individuals aged from a
fetus to 80 years. Twelve autism and 9 schizophrenia patients were also
included in the study.
The
study was the first of its kind which compares vitamin B12 levels in the brain
across our lifetime. The levels of vitamin B12 were ten times higher in the
youngest compared with the oldest.
The
decline of B12 levels in brain in older age is not bad but it is detrimental in
young age. Low levels of vitamin B12 have many negative consequences for young
people.
Researchers
found the same levels of vitamin B12 in the people of under 10 years of age
with autism and 57 years of age. But it was unclear what those low levels of
B12 implied.
Various
kinds of researches have searched for a link between neurological disorder and
vitamin deficiencies. But no specific study was conducted.
