ago. I slowly processed to going from a walker to a cane and then walking independently. I feel my symptoms are coming back. The OH started months ago and getting worse. Then I get lightheaded and my mind gets fuzzy like I have dementia. Forget things. Supposedly I have mild cognitive condition. I thought Parkinsonism was not progressive?

I recently went through months of OH. It was due to two drugs interacting. Adjustments made by Dr. It really pays to attend to medication side effects. The Dr. Can't remember everything all the time .

Is it normal to experience cognitive changes when lightheaded from orthostatic hypotension (OH)?

The fuzzy thinking and forgetfulness you're experiencing when lightheaded could be related to the OH itself rather than dementia. When blood pressure drops and you feel lightheaded, your brain may temporarily receive less oxygen, which can cause confusion and memory issues in that moment.

However, it's important to discuss these symptoms with your doctor, especially since you mention having a mild cognitive condition. Cognitive changes can occur in Parkinson's and related conditions, and they can range from mild issues with memory and concentration to more significant changes.

Regarding drug-induced parkinsonism: While it's often considered potentially reversible if the causative medication is stopped, some people do experience persistent or progressive symptoms. The progression you're describing—symptoms returning after improvement—warrants a conversation with your neurologist.

Your worsening OH and returning motor symptoms need medical attention. Your doctor may need to:

* Adjust medications that might be contributing to OH
* Evaluate whether your cognitive symptoms are from OH, medication side effects, or progression
* Rule out other causes like infections or dehydration
* Consider whether your diagnosis needs reassessment

Don't wait to reach out to your healthcare team about these changes.
