Temporal Muscle Thickness as a New Biomarker: Its Association With Alzheimer Pathology and Cognitive Impairment in Chinese Adults
Yunxia Zhu, Yingying Ke, Chenxi Ren, Jiehua Zhu, Zhen Zhang, Liang Cui, Yuehua Li, Fang Xie et al.. Journal of Cachexia Sarcopenia and Muscle, 2025-07-28
Topic: Amyloid, tau and blood-test diagnosis
Results Significant differences in TMT measurements were observed by age and sex, with thinner TMT found in females and older adults. TMT was significantly associated with ASMI, handgrip strength and mobility. Among cognitive domains, TMT was most closely associated with performance on the Auditory Verbal Learning Test recognition (p < 0.05). Stratified analyses revealed that the correlation between TMT and MoCA‐B remained significant in MCI participants but not in AD participants. Multivariable logistic regression analysis showed that higher TMT was significantly associated with a lower risk of MCI (OR: 0.494, 95% CI: 0.287–0.849, p < 0.05) and a reduced likelihood of functional dependence (OR: 0.791, 95% CI: 0.670–0.935, p < 0.01). Furthermore, TMT was lower in participants with higher brain tau deposition and was negatively associated with tau PET Braak stages (both p < 0.01). Conclusions A decline in TMT was associated with worse cognitive function, increased cerebral tau deposition and impaired functional performance.

Key findings
- Results Significant differences in TMT measurements were observed by age and sex, with thinner TMT found in females and older adults.
- TMT was significantly associated with ASMI, handgrip strength and mobility.
- Among cognitive domains, TMT was most closely associated with performance on the Auditory Verbal Learning Test recognition (p < 0.05).
- Stratified analyses revealed that the correlation between TMT and MoCA‐B remained significant in MCI participants but not in AD participants.
- Multivariable logistic regression analysis showed that higher TMT was significantly associated with a lower risk of MCI (OR: 0.494, 95% CI: 0.287–0.849, p < 0.05) and a reduced likelihood of functional dependence (OR: 0.791, 95% CI: 0.670–0.935, p < 0.01).
Why it matters
This study found that thinner temporal muscle thickness was associated with worse cognitive function, higher brain tau deposition, and impaired functional performance in Chinese adults. The link between temporal muscle thickness and cognitive scores remained significant in people with mild cognitive impairment but not in those with Alzheimer's disease.
