Is the use of high-intensity atorvastatin associated with memory impairment?

Area of Science:

• Cardiology
• Neuroscience
• Pharmacology

Background:

• High-intensity statins are crucial for managing Acute Coronary Syndromes (ACS).
• The impact of statins on neurocognition, particularly memory, remains less understood.
• Atorvastatin is a commonly prescribed high-intensity statin.

Purpose of the Study:

• To investigate the effect of high-intensity atorvastatin on memory in statin-naïve ACS patients.
• To assess changes in cognitive function using validated memory scales before and after statin initiation.

Main Methods:

• Prospective observational study involving middle-aged, statin-naïve ACS patients.
• Administration of guideline-directed high-intensity atorvastatin (40 mg).
• Memory assessment using the Post-Graduate Institute Memory Scale (PGI-MS) and Logical Memory Passage Test (LMPT) at baseline and 6 months.

Main Results:

• No significant difference in mean PGI-MS scores (p=0.26) or composite scores (p=0.20) after 6 months.
• A statistically significant, though small, improvement was observed in immediate recall (p=0.05) and delayed recall (p=0.002).
• Overall memory function was not adversely affected by high-intensity atorvastatin therapy.

Conclusions:

• High-intensity atorvastatin therapy did not significantly impair memory in middle-aged, statin-naïve ACS patients at 6 months.
• While some specific recall functions showed minor improvements, global memory remained stable.
• These findings suggest that atorvastatin can be safely used in this patient population without significant cognitive detriment.
