Short Summary
Main recommendation: Dr. Berry says people with normal cognition or mild cognitive impairment who take lipophilic statins should avoid them and discuss switching with their doctor, while monitoring cognitive status closely if taking hydrophilic statins or PCSK9 inhibitors. The video cites a study of 392 participants reporting that lipophilic statin users had more than double the dementia risk compared with non-users.
Key Points
- The study grouped participants by baseline cognitive status, baseline cholesterol levels, and the statin type they were already taking, using both subjective and objective cognitive testing.
- Lipophilic statins named in the video are atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Mevacor), pitavastatin (Livalo), and simvastatin (Zocor).
- Hydrophilic statins that did not show the same doubled risk in the video are pravastatin (Pravachol) and rosuvastatin (Crestor).
- PCSK9 inhibitors evolocumab (Repatha) and alirocumab (Praluent) were not studied, so their dementia risk remains undetermined.
- PET scans of lipophilic statin users showed a significant drop in metabolism in the posterior cingulate cortex, an area most affected in Alzheimer's dementia.
Details Worth Noting
- Concrete instructions: Check whether your cholesterol medication is one of the lipophilic statins listed above. If it is and you have normal cognition or early cognitive decline, Dr. Berry advises avoiding these drugs entirely and asking your doctor about switching, rather than stopping on your own. If you take a hydrophilic statin or a PCSK9 inhibitor, the video advises monitoring your cognitive status closely. Share the video with anyone taking a cholesterol medication so they can check their own prescription and call their doctor.
- The speaker, Dr. Ken Berry, is a family physician; the video presents the study findings and does not provide individualized medical advice.
- The findings come from one study of 392 participants, and the video links the research in its description; the speaker's claims should be checked against the full paper.
- The video invites viewers to share any memory or cognitive changes they noticed while taking cholesterol medication in the comments.
Bottom Line
The video reports a study linking certain statins to a higher dementia risk, but its findings are limited to one study and do not establish cause and effect for all patients. Anyone concerned about their cholesterol medication should review it with their own doctor rather than stopping it on their own.
