long Covid are caused by the protein clumps in the brain. The protein clumps were similar to those that lead to Alzheimer's disease and dementia.
The study also shows similarities between the effects of Covid-19 and the early stages of diseases such as Alzheimer’s and Parkinson’s.
However, the researchers have also cautioned that the implications of these changes were "unclear". The changes also don't necessarily suggest that people might have lasting damage or that they may profoundly affect thinking, memory, or other functions, they said.
If further research confirms that the amyloid clumps or abnormal protein clumps -- a hallmark of Alzheimer's -- are contributing towards the long Covid, the drugs that are being used to treat Alzheimer's and Parkinson's may be remodeled to treat these debilitating neurological symptoms.
