Are higher total serum cholesterol levels associated with better long-term motor function after ischemic stroke?

Area of Science:

• Neurology
• Cardiovascular Medicine
• Rehabilitation Science

Background:

• Ischemic stroke significantly impairs motor function, leading to long-term disability.
• Understanding prognostic factors is crucial for predicting recovery and guiding rehabilitation strategies.
• Total cholesterol (TC) levels are a modifiable risk factor with potential implications for stroke outcomes.

Purpose of the Study:

• To investigate the prognostic significance of total cholesterol (TC) levels on long-term motor function following ischemic stroke.
• To determine if higher TC levels are associated with better motor recovery after stroke.
• To identify predictors of motor function recovery in ischemic stroke patients.

Main Methods:

• A cohort of 114 ischemic stroke patients was divided into high TC (HTC) and low TC (LTC) groups.
• Motor function was assessed using the Fugl-Meyer assessment motor score (MFMA) at baseline and up to 12 months post-stroke.
• Linear mixed regression models were employed to analyze prognostic factors for serial MFMA scores.

Main Results:

• Higher TC levels were associated with significantly better long-term motor function recovery.
• The high TC group demonstrated higher MFMA scores compared to the low TC group (2.72 units higher).
• Baseline MFMA scores, basal ganglion lesions, and first-time stroke were also significant predictors of motor recovery.

Conclusions:

• Elevated total cholesterol in the acute phase of ischemic stroke serves as a favorable prognostic indicator for long-term motor function.
• These findings suggest a potential role for cholesterol management in stroke recovery.
• Further research is warranted to explore the mechanisms underlying this association.
