Well this is rather improbable, particularly as a cause of weight gain in
three of four people after head injury or brain surgery, but what the heck.
There are rare cases of people suffering damage to the hypothalamus
(usually from a tumour) who show sometimes astonishing increases in weight.
The classic case of that of Reeves and Plum (1969) of a young woman with
an inoperable hypothalamic tumour who gained just under one pound a day
for two months. The condition has a well-known experimental counterpart
in rats, called the "hypothalamic hyperphagic syndrome". If your brain
injury impinged on the hypothalamus, particularly the medial region, it
might be worth considering.
