Menene Zai Faru Idan Daya Daga Al'amuran Farko na Cutar Alzheimer Ba Tangles, Plaques, Ko Protein Ba, Sai Ma'adanin Trace Da Ya Manke?

Takardar da aka wallafa a mujallar Nature a shekarar 2025, daga dakin bincike na Bruce Yankner a Harvard Medical School, ta ba da wani sabon hangen nesa. A cikin binciken, lithium ne kadai ƙarfe da aka ga yana raguwa a kwakwalwan mutanen da ke da mild cognitive impairment (MCI). Lokacin da masu bincike suka rage sinadarin lithium a berayen, dabbobin sun haɓaka al'amuran da ke kama da alamomin Alzheimer. Idan aka ba su lithium orotate, waɗannan al'amuran sun tsaya.

Wannan bincike yana da muhimmanci, amma yana bukatar a duba shi da hankali. Ga abin da aka gano da kuma abin da ba a gano ba.

Sakamakon Binciken Da Ya Shafi Mutane: Karfe Daya Kawai Ya Bayyana

Kungiyar ta auna matakan karafa a kwakwalwa daga manyan ƙungiyoyin tsufa da suka haɗa da Rush Alzheimer's Disease Center. Suka kwatanta kwakwalwan mutane masu ƙwaƙwalwar al'ada, MCI, da kuma Alzheimer.

Daga cikin dukkan ƙarafe da aka auna, lithium ne kawai da aka ga yana raguwa sosai a kwakwalwan masu MCI – matakin da ke ƙara yuwuwar kamuwa da Alzheimer. Wannan na nuni da cewa asarar lithium ba wai sakamakon cutar ba ne kawai, watakila alamar na faruwa tun da wuri, kafin manyan alamomin su bayyana.

Amyloid‑beta Yana Rike Lithium

A cikin ciwon Alzheimer gaba ɗaya, amyloid‑beta plaques suna ɗaukar lithium, suna haɗa shi sannan hakan ke ƙara ragin lithium da ke samuwa a kwakwalwa. Wannan na iya haifar da zagaye maras kyau: karancin lithium → ƙarin amyloid → ƙarin rike lithium.

Kamar yadda aka gano a cikin ƙwayoyin mutum, babu tabbacin cewa asarar lithium ke haifar da cutar; amma wannan shine dalilin da ya sanya gwaje‑gwajen beraye ke da mahimmanci.

Gwajin Rage Lithium a Berayen

Don gwada alaƙar, masu bincike sun rage adadin lithium a abincin berayen da ba su da wata cuta da kuma a cikin berayen da suka ƙunshi alamomin Alzheimer. Lithium a fatar kwakwalwa ya ragu kusan kashi 50%, kuma sakamakon ya fito da wadannan al'amura:

Ƙaruwa a taruwar amyloid‑beta a kwakwalwa
Ƙaruwa a phosphorylated tau, alamar tattare‑tangle
Haɓakar ƙwayoyin microglial masu haifar da kumburi (ƙwayoyin garkuwar jiki sun shiga yanayin lalata)
Raguwar synapses, axons, da myelin – igiyoyin haɗin ƙwaƙwalwa da rufin su
Saurin raguwar tunani

Single‑nucleus RNA sequencing ya nuna cewa ƙarancin lithium ya canza fassarar kwayoyin a nau’o’in ƙwayoyin kwakwalwa da dama, kuma waɗannan canje‑canje sun yi daidai da sauye‑sauyen da aka gani a ƙwalwar mutane masu Alzheimer. Ba kawai alamomi ba ne suka yi kama; ƙwayoyin kansu sun soma ɗaukar yanayin da ya yi kama da Alzheimer.

Abin da ya fi burgewa shi ne, wannan ya faru a berayen da ba a gyara ba (wild‑type mice), ba kawai a cikin dabbobin da aka ƙirƙiri su haifar da amyloid ba. Karancin lithium kaɗai ya isa don jefa al'amura cikin yanayin da ba daidai ba.

Maganin Da Aka Gwada: Lithium Orotate

Masu bincike sun kuma gwada lithium orotate a ƙananan ƙima. Wannan sinadari ya dakatar da canje‑canjen da ke nuna cuta da kuma asarar ƙwaƙwalwa a cikin berayen da suka ƙunshi alamomin Alzheimer da kuma berayen da suka tsufa ba tare da wata cuta ba. An yi amfani da micro‑dose mai ƙasa da adadin da ake amfani da shi a maganin psychiatric na lithium carbonate.

Wannan ɓangare ne da ya ja hankalin jama’a a intanet, amma yana bukatar a lura da cewa sakamakon ya samo ne daga gwaje‑gwajen beraye kawai.

Me Ya Sa Orotate? Rike Shi Da Amyloid Ya Rage

Idan amyloid‑beta ke rike lithium, ƙara wani ƙarfe na al'ada ba zai iya yanka illa ba, domin plaques za su ci gaba da ɗaukar lithium. Kungiyar ta gano cewa lithium orotate yana da ƙarancin haɗin kai da amyloid idan aka kwatanta da wasu salts na lithium. A zahiri, ya fi sauƙin wucewa “mamayar” plaque kuma yana kasancewa bioavailable.

Wannan shine hujjar da ke bayan niyyar takardar cewa maye gurbin lithium da “salts masu gujewa amyloid” na iya zama hanya zuwa rigakafi da magani. A nan, ba lithium kaɗai ba, sai nau'in da ake amfani da shi ne mabuɗi.

Hanyar Aiki: GSK3‑Beta

Tasirin ƙarancin lithium yana mediated da kinase GSK3‑beta. Wannan enzyme ana sanin lithium na rage aikinsa, kuma yana da alaƙa da tau phosphorylation, sarrafa amyloid, da kumburi. Lokacin da lithium ke ƙasa, aikin GSK3‑beta yakan ƙaru, wanda ke haifar da ƙarin phospho‑tau da neuroinflammation da aka gani.

Kalmar “aƙalla a wani ɓangare” tana da muhimmanci. Wataƙila wasu hanyoyi ma suna taka rawa, kuma ba a ƙare gano cikakken tsarin ba.

Abin Da Wannan Ba Ya Nuna Ba

Gaskiya tana da muhimmanci, don haka a tsaye:

Babu wani gwaji na mutum da aka gudanar a cikin yanayi na randomized controlled trial (RCT) na lithium orotate don rigakafi ko maganin Alzheimer.
Sakamakon daga beraye ba koyaushe ake fassara su zuwa mutane ba, kuma Alzheimer na da tarihin gwaje‑gwajen dabbobi da suka kasa tabbatta a mutane.
Bayanan kwanakin mutuwa na mutane su ne associative kawai, ba dalili‑dalili ba.
Lithium yana da narrow therapeutic index; dogon amfani da manyan ƙudade na iya haifar da matsalolin koda, thyroid, da kuma hadin gwiwa da wasu magunguna.

Binciken ba ya ba da umarnin kowa ya fara shan ƙarin lithium.

Tambayar Kayan Ƙari

Samfuran low‑dose lithium orotate ana sayar da su a kasuwannin ƙari, galibi suna ba da 1‑5 mg na elemental lithium a kowanne kofi. Sha'awar su ta ƙaru sosai tun bayan bayyana takardar. Amma kasuwar ƙari ba ta da tsarin da ya yi daidai da gwajin beraye da aka yi, kuma ingancin samfuran na iya bambanta sosai.

Duk wanda ke tunanin ɗaukar lithium – ko da a micro‑dose – ya kamata ya tuntuɓi likita da farko. Abubuwan da za a tattauna sun haɗa da:

Aiki na koda: Lithium yana fita ta koda, don haka a duba yanayin koda na asali da na dindindin.
