Saco-Indonesia.com - Dari penelitian terbaru di Ohio State University dan Institute for behavioral Medicine Research, cedera pada otak dan gegar otak bisa menyebabkan depresi setelah beberapa tahun.

Penelitian ini menunjukkan bahwa sel-sel mikro pada otak tikus cenderung waspada pada tingkat tinggi setelah mengalami cedera. Hal ini menyebabkan sel otak lebih mudah mengalami peradangan dan menyebabkan depresi dalam jangka waktu yang panjang, seperti dilansir oleh Softpedia.

Penelitian menemukan bahwa orang yang mengalami gegar otak berkali-kali dalam hidupnya biasanya mengalami masalah mental setelah beberapa tahun. Namun peneliti belum bisa menjelaskan mengapa hal ini bisa terjadi.

"Banyak orang yang pernah mengalami cedera pada bagian otak tidak mengalami masalah mental hingga mereka berusia 40 tahun, 50 tahun, atau 60 tahunan," ungkap peneliti.

Hal ini menunjukkan bahwa ada faktor lain yang menyebabkan orang yang mengalami cedera otak dan gegar otak pada akhirnya akan memiliki masalah dengan kesehatan mental seperti stres atau lebih mudah depresi.

KATHMANDU, Nepal — When the dense pillar of smoke from cremations by the Bagmati River was thinning late last week, the bodies were all coming from Gongabu, a common stopover for Nepali migrant workers headed overseas, and they were all of young men.

Hindu custom dictates that funeral pyres should be lighted by the oldest son of the deceased, but these men were too young to have sons, so they were burned by their brothers or fathers. Sukla Lal, a maize farmer, made a 14-hour journey by bus to retrieve the body of his 19-year-old son, who had been on his way to the Persian Gulf to work as a laborer.

“He wanted to live in the countryside, but he was compelled to leave by poverty,” Mr. Lal said, gazing ahead steadily as his son’s remains smoldered. “He told me, ‘You can live on your land, and I will come up with money, and we will have a happy family.’ ”

Weeks will pass before the authorities can give a complete accounting of who died in the April 25 earthquake, but it is already clear that Nepal cannot afford the losses. The countryside was largely stripped of its healthy young men even before the quake, as they migrated in great waves — 1,500 a day by some estimates — to work as laborers in India, Malaysia or one of the gulf nations, leaving many small communities populated only by elderly parents, women and children. Economists say that at some times of the year, one-quarter of Nepal’s population is working outside the country.
