Most patients do not show signs of disorder before 15 years, although the previous neurologists assumed that this process begins in the womb. Now there is increasing evidence supporting this idea, but the exact mechanisms are not yet known.
The causes of schizophrenia has long remained a mystery to scientists, but a new study has confirmed the link between vitamin D deficiency at birth and the development of schizophrenia in adulthood. There is fairly strong evidence that the process is associated with genes, and in some cases has a value of several factors.
We know that vitamin D is vital for the absorption of calcium in the bones, and its deficiency can lead to such disorders as osteoporosis and rickets, but its full range of functions in the body are not yet known. In a new study published in the journal Scientific Reports, the staff of the brain Institute University of Queensland in Australia under the leadership of neurologist John McGrath (John McGrath) in cooperation with Aarhus University (Denmark) has determined that this substance may play a role in the development of schizophrenia.
Scientists took a 2 602 a person born between 1981 and 2001 who were diagnosed with schizophrenia, and examined the concentration of vitamin D in blood samples taken from these people in infancy. For selected information from the Danish national register and database of anonymous health information, which is used to study trends and statistics of health. It turned out that 44 percent of babies who have observed the deficiency of vitamin D at birth increased risk of schizophrenia in adulthood.
