Mhedziso yokuti kuva nehomanana zvinwiwa zvakawanda zvinouraya zvachose masero europi ave aripo kwenguva yakati. Kugara kwenguva refu kunwa kwakagara kwakabatanidzwa nekusaona kwepfungwa. Kunwa doro panguva yakaoma yekukura kweuropi, yakadai seprenti kana makore ekuyaruka, inonyanya kuipa. Asi kuva negirazi iro rewaini mushure mekudya kwekudya kwakakuisa iwe panjodzi yekurasikirwa neural?
Zvidzidzo Zvinoratidze Nezve Doro uye Masero eBongo
Nyanzvi dzinofunga kuti kunwa hakusi kutungamirira kuuropi yesero rufu. Kutaura zvazviri, vatsvakurudzi vakaona kuti kunwa kwakanyanyisa kunogona kuva nehutano hwakawanda huripo, kusanganisira kukwanisa kugadzirisa pfungwa uye kuderedza chelesterol.
Chimwe chekudzidza chakafananidzira kuenzanisa nhamba yeeuroni inowanikwa muurwere hwevakadhakwa nevasina zvinodhaka dzakawana kuti pakange pasina kuve kwehana neocortical neurons pakati pemapoka maviri.
Kunyange kunyanya kunwa doro uye kushandiswa kwenguva refu kwekushandisa doro hakuiti zvakakonzera rufu rwemasero europi. Pane kudaro, doro rinokuvadza dendrites iri mu cerebellum uye inoderedza kukurukurirana pakati peeurons. Vatsvakurudzi vakaona kuti doro rinoshandisa kwete kungovhiringidza kutaurirana pakati peeuron; inogonawo kuchinja maitiro avo. Chinhu chimwe chete hachiiti, chavakawana, chinouraya masero.
Muzvokwadi, zvidzidzo zvinosanganisira makonzo dzakawanikwa kuti kumira kunwa doro - kunyange mushure mokunge kushandiswa kusingaperi - kunobvumira uropi kuporesa.
Doro uye Bongo Zvinokuvadza
Kunyange zvazvo kufa kwechirwere chepachivande kungasakonzerwa nekudhakwa, kunwa doro zvisina kufanira kunogona uye kunotungamirira kukanganisa kwehupi . Kushandiswa kwenguva refu kwechinwiwa chinodhaka kunogona kutungamirira kushayikwa muB vitamin inokosha inonzi thiamine. Izvo zvinoshaya zvinogona kukonzera Wernicke-Korsakoff syndrome, chirwere chakakomba chepfungwa chinosanganiswa nedoro rinoshandiswa chinoita kuti kurasikirwa kweeuroni muuropi.
Iyo chirwere chinoratidzirwa nezvinetso zvekuyeuka, amnesia, nekushayikwa kwemisumbu kuwirirana. Muchiitiko ichi, zvakakosha kuziva kuti kurasikirwa kweeuroni kunokonzerwa nekushaya simba kwe thiamine, kwete neicho chaicho chekushandisa doro.
Zviri pachena kuti izvi hazvirevi kuti vanhu havafaniri kuchengetedza ngozi dzingangodaro doro. Sangano reNational Institute on Alcohol Abuse and Alcoholism rinotaura kuti zvimwe zvinhu zvinogona kukonzera kunyatsoita kunoita doro kunokanganisa uropi, kusanganisira kuti munhu anonwa zvakadini uye nguva yakawanda sei, nguva yakareba sei munhu ari kunwa, kusununguka kunwa doro, uye nyika yose hwehutano hwemunhu.
Chimwe chinhu chokufunga nezvacho: Kunyange zvazvo doro risingagoni "kuuraya" masero europi, tsvakurudzo inoratidza kuti huwandu hunodhaka doro hunogona kukanganisa neurogenesis kana kuumbwa kwemasero matsva europi. Kusvikira munguva pfupi yapfuura, nyanzvi dzakawanda dzaidavira kuti vanhu vakuru vakanga vasingakwanisi kukura neuroni itsva muuropi. Izvo zvenhema kubvira kare zvakadzingwa, uye nyanzvi dzouropi dzinoziva kuti nzvimbo dzakasiyana dzeuropi dzinopfuurira kuumba masero matsva kunyange kusvika pakukwegura.
The Bottom Line
Vatsvakurudzi vanodavira kuti doro harusi kuparadza masero europi. Zvinogona, zvisinei, zvinokanganisa utano hwehuropi uye huine zvimwe zvakakomba zvehutano.
