Hi
This may be true, but there is low quality evidence for it. The opposite is overwhelmingly true.
Here are quotes from recent journal articles: "Individuals of 50 years and older who were prescribed statins had a substantially lowered risk of developing dementia, independent of the presence or absence of untreated hyperlipidaemia, or exposure to non-statin LLAs."
"Based on epidemiologic studies as well as case reports, a risk of peripheral neuropathy associated with statin use may exist; however, the risk appears to be minimal. On the other hand, the benefits of statins are firmly established."
I point this out only to alert readers that when considering which medicines to take or not, they should avail themselves of the latest scientific information, which is often very hard for an untrained layman. That's what medical providers are for.
