77 percent of those who have the syndrome have symptoms that resemble those of Alzheimer's disease as they get older. Typical neurodegenerative illnesses and gradual loss of scent are also commonly seen from the prepubertal period, with males potentially experiencing sexual maturation problems. Recent research has revealed that the neurons producing gonadotropin-releasing hormone, which is known for controlling reproduction through the hypothalamus, may also have an impact on other brain regions that may be involved in cognitive processes.
