A Canadian resident who suffered a stroke did not feel hungry for more than a year — this is the first such case in history, writes the scientific journal Neurocase, citing experts from the University of Montreal.
A pregnant 28-year-old woman was admitted to the hospital with paralysis of the right side of her body and speech disorders. Doctors, with the help of MRI, diagnosed her with an acute ischemic stroke of the left insular lobe of the brain.
After discharge, the patient took only acetylsalicylic acid. Six months later, her condition improved, but she noticed that she never felt hungry during this time and, therefore, inadvertently missed meals.
Doctors conducted an examination and found out that even with a lack of calories, the Canadian did not receive any physiological signals that it was time for her to eat. She also had no problems with the taste and smell of food.
The woman began to feel hungry again only 15 months after the stroke. During this time, she lost ten kilograms.
According to the head of the study, Dang Khoa Nguyen, the cause of this condition was damage to the part of the brain responsible for processing taste signals, appetite, and energy balance.
Thus, the stroke provoked an imbalance of the autonomic nervous system and increased sympathetic function, which, in turn, contributed to a decrease in appetite.
