In clinical research, 49 participants were divided into four groups: healthy controls (HC, n\u2009=\u200911), insomnia with normal cognition (IS, n\u2009=\u200914), mild cognitive impairment without insomnia (MCI, n\u2009=\u200910), and insomnia with mild cognitive impairment (IS-MCI, n\u2009=\u200914). Magnetic resonance spectroscopy (MRS) was used to evaluate the neural \u03b3-aminobutyric acid (GABA) and glutamate\u2013glutamine (Glx) in bilateral thalamus. In experimental studies, the rat model of sleep deprivation combined with amyloid-\u03b2 (A\u03b2) injection was established, after behavior testing, the levels of Glx, choline (Cho) and N-acetyl aspartate (NAA) in the bilateral hippocampus were evaluated with MRS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The patients in the IS-MCI group exhibited significantly lower GABA level than IS, MCI and HC groups.
