Brain fog is not always “just stress” or “just aging.”
Sometimes, it may be connected to medications people take every single day.
In this article, I discuss several commonly prescribed medications that research has linked to cognitive issues, memory problems, or increased risk of brain fog — including:
• Anticholinergics
• Benzodiazepines
• Sleep medications
• Proton pump inhibitors
• Opioids
• Certain psychiatric medications
Many people are never warned about these potential side effects.
That doesn’t mean you should stop taking your medications abruptly, but it does mean these conversations are worth having with your healthcare team.
If you’ve been struggling with mental fatigue, forgetfulness, poor focus, or feeling like your brain isn’t functioning the way it used to, this article may help connect some important dots.
