This study examined the regulatory effects of Acceptance and Commitment Therapy (ACT) on T lymphocyte subsets, serum inflammatory cytokines, neurotrophic factors, antioxidant enzymes, and lipid peroxidation products in elderly cerebral stroke (CS) patients, providing insights into the multi-dimensional pathophysiological interactions and potential intervention strategies for chronic stroke recovery. In this randomized controlled trial, 120 elderly stroke patients were allocated to either an ACT group (ACT intervention; n = 60) or a routine group (conventional treatment; n = 60). Comprehensive assessments were performed to quantify: (1) peripheral T lymphocyte distribution (CD3+, CD4+, CD8+ subsets, and CD4+/CD8+ ratio), (2) serum inflammatory cytokines (IL-1p, IL-6, IL-10, and TNF-a), (3) neurotrophic factors (5-HT, NE, BDNF, and IGF-1), and (4) antioxidant enzymes (SOD, CAT) and lipid peroxidation products (MDA, NO) using flow cytometry, HPLC-ECD, and ELISA. Statistical analyses were conducted with SPSS 22.0. Following treatment, CS patients exhibited reduced CD3+ and CD4+ T-cell levels along with a decreased CD4+/CD8+ ratio, while CD8+ T-cell proportions were elevated (P< 0.05). Proinflammatory cytokine levels (IL-1 b, IL-6, and TNF-a) were significantly suppressed, whereas anti-inflammatory IL-10 expression increased (P < 0 .0 5 ). Notably, ACT demonstrated superior efficacy in restoring immune balance and attenuating inflammation compared to conventional intervention (P< 0.05). Furthermore, neurotrophic factors levels were elevated, and oxidative stress markers were ameliorated in CS after treatment (P< 0.05), suggesting that ACT enhances neurotrophic activity and mitigates oxidative injury. ACT likely confers neuroprotection through multi-target mechanisms, including modulation of T-cell subset homeostasis, upregulation of neurotrophic factors, and suppression of oxidative stress.
