Surgeons and pediatricians in India have been puzzled after discovering a 26-year-old man trapped inside the body and mind of a child aged between one and two years.

Jerly Lyngdoh – who is still dressed in baby clothes by his parents – has a head circumference that babies 9-12 months old have, measures 84 cm like any two-year-old and weighs 22 pounds.

“Jerly’s infantile features are remarkable, and the only things he shares with an adult are his teeth,” Dr. J. Ryndong told the Hindustan Times.

According to the pediatrician, Lyngdoh suffers from poor secretion of growth hormones from the pituitary gland.

“His is a case opposite to progeria, which means advanced ageing, and we have reasons to say Jerly is a rarity,” Ryndong added. He ruled out the genetic factor, since all six of Jerly’s siblings have no physical or mental disability.

“We also plan to seek expertise from the medical world beyond to crack Jerly’s case,” the doctor said.
