Hippocampus da cutar Alzheimer

by Esther Heerema, MSW; Binciken by Claudia Chaves, MD

Hippocampus wani yanki ne na kwakwalwa kawai a ƙarƙashin lobes. Ya yi kama da siffar teku, kuma akwai daya a kowane gefen kwakwalwa a sama da kunnuwan.

Hippocampus yana taimaka mana inganta sabon tunanin . Ana duba shi a wani lokuta a matsayin ƙofar don tunanin kamar idan tunanin yana buƙatar shiga cikin hippocampus don a iya adana shi cikin bankin ƙwaƙwalwar ajiya na dogon lokaci .

Wasu bincike sun nuna cewa hippocampus yana da mahimmanci don ba kawai yin sabon tunanin ba har ma da sake dawo da tsohuwar tunanin.

Abin sha'awa, hippocampus a gefen hagu sau da yawa yana da babban aiki a ƙwaƙwalwar ajiya da harshe fiye da ɗaya a gefen dama.

Yadda Cututtukan Alzheimer ke Cutar da Hippocampus

Bincike ya gano cewa daya daga cikin bangarori na farko a cikin kwakwalwa cutar Alzheimer ke cutar shi ne hippocampus. Masana kimiyya sun haɗu da lalata (shrinkage) na wuraren hippocampal tare da kasancewar cutar Alzheimer. Atrophy a cikin wannan sashin kwakwalwa yana taimakawa wajen bayyana dalilin da ya sa daya daga cikin bayyanar cututtuka na cutar Alzheimer shine sau da yawa ƙwaƙwalwar ƙwaƙwalwar ajiya, musamman ma ƙaddamar da sabon tunanin.

Hijocampus atrophy kuma an haɗu da kasancewar gina jiki mai gina jiki kamar yadda cutar Alzheimer ta ci gaba.

Saboda haka, girman da girma na hippocampus yana da cutar Alzheimer.

Amma yaya game da rashin tausayi na rashin hankali, yanayin da wani lokacin, amma ba koyaushe, ci gaba da cutar Alzheimer ba?

Nazarin da aka nuna sun nuna cewa asrophy na hippocampus ya danganta da rashin rashin lafiya . A gaskiya ma, an nuna girman girman hippocampus da rawanin da aka yi masa na hasashen cewa ko MCI na cigaba da cutar Alzheimer ko a'a.

Ƙaramin ƙarancin hippocampal ƙarami da sauri ko yin shrinkage ya dace tare da ci gaba da dementia.

Shin bambancin Hippocampal zai iya bambanta tsakanin iri-iri daban-daban?

Ɗaukar bincike da yawa sun auna girman girman hippocampal kuma ya dubi yadda yake da alaka da wasu nau'in nakasa. Wata mawuyacin shi shine likitoci zasu iya amfani da ƙwayar atrophy a yankin hippocampal don gano ainihin irin abin da ke cikin damuwa.

Alal misali, idan cutar Alzheimer ita ce kawai nau'in nakasar da ya shafi girman hippocampus, ana iya amfani da shi don ya gwada Alzheimer. Duk da haka, bincike da yawa sun nuna cewa wannan ma'auni ba sau da amfani wajen gane bambancin launuka.

Ɗaya daga cikin binciken da aka buga a mujallar Neurodegenerative Diseases ya lura cewa raguwar hippocampus ya auku a cikin ƙwayar cuta .

Wani bincike na biyu ya gano cewar an rage girman hawan hippocampal tare da lamenta na gaba .

Masana kimiyya sun gano wani bambanci mai ban mamaki, duk da haka, idan aka gwada lafiyar Lewy tare da cutar Alzheimer. Lement jikin jiki yana nuna nisa da yawa daga wurare masu hippocampal a cikin kwakwalwa, wanda ya dace daidai da rashin tasiri a ƙwaƙwalwar ajiya, musamman ma a farkon matakan Lewy jiki .

Za ku iya hana Hippocampus daga Kashewa?

Rashin filastik (wani lokaci don ƙwaƙwalwar kwakwalwa don girma da canji a lokacin) na hippocampus an nuna ta akai-akai a bincike. Bincike ya gano cewa, kodayake hippocampus na cigaba da tayarwa yayin da muka tsufa, aikin motsa jiki da haɓaka na zuciya (aikin motsa jiki) na iya jinkirin raguwa kuma, a wasu lokuta, har ma ya juya baya.
