Hōʻike ʻia nā kumu o ka manaʻo ʻole a me ka huhū i ka maʻi o Alzheimer

Ua ʻike mua nā mea noiʻi ma ke Kula Nui o ka Lapaʻau ʻo Indiana (USA) i ke ʻano molekala e pili ana i nā hōʻailona neuropsychiatric ma mua o ka emi ʻana o ka naʻauao i ka maʻi o Alzheimer. Ke kamaʻilio nei mākou e pili ana i ka nalowale o ka hoʻoikaika ʻana, ka manaʻo ʻole, ka hopohopo, ke ʻano o ka naʻau a me ka hoʻonui ʻana i ka huhū.

Ua nānā ka poʻe ʻepekema i ka nucleus accumbens, kahi ʻāpana o ka lolo e hana nui i ka ʻōnaehana uku. Mai ka nucleus accumbens ka hopena o ka ʻike hoʻoikaika. 

Ua ʻike nā mea noiʻi he loaʻa nā mea hoʻokipa i ka poʻe maʻi o Alzheimer i ka nucleus accumbens e hiki ai i ka calcium ke komo i nā neurons. ʻO ka mea maʻamau, ʻaʻole pono e loaʻa nā mea loaʻa i ka nucleus accumbens. ʻO ka nui o ka calcium e alakaʻi i ka make o nā neurons a me ka nalo ʻana o nā pilina synaptic ma waena o lākou, kahi e hōʻailona ai i nā hōʻailona neuropsychiatric.

Ma muli o kēia, ʻōlelo ka poʻe ʻepekema ʻo ka hoʻopaʻa ʻia ʻana o nā mea loaʻa calcium i ka nucleus accumbens hiki ke pale a hoʻopaneʻe paha i ka hoʻomaka ʻana o ka maʻi o Alzheimer.
