Low IQ in childhood associated with a high risk of Alzheimer's disease
Prevention of Alzheimer's disease in carriers should begin as early as possible.
This was reported by experts, informs Neurobiology of Aging. It became known that the genetic variant, which is associated with Alzheimer's disease, negatively affects cognitive abilities in early childhood. By the way, only 15% of the population has it.
Even one copy of the genetic variant increases the probability of Alzheimer's disease 3 times.
It is assumed that cognitive abilities begin to decline in childhood.
The researchers compared the IQ of children aged 6 to 18 years. An analysis of the boys' genomes showed that each APOE4 allele reduces IQ by an average of 2 points; for girls, they experienced a decrease of 3 points.
