	New hope for Parkinson's patients through stem cell technology? A contribution by Jürgen Zender

An innovative procedure from stem cell medicine could alleviate symptoms in Parkinson's patients in the future. The researchers rely on lab-grown neurons that are inserted into the brains of patients to produce the essential neurotransmitter dopamine.

Novelty of the procedure:
– Using neurons from the lab to produce dopamine in the brain.
– Neurons created using embryonic stem cell technology are designed to form synapses and behave like their own brain cells.
– The aim of the procedure is to reduce the devastating symptoms of Parkinson’s, mainly movement problems.

Researchers hope:

- Initial data indicate that the implanted cells survive one year after treatment and reduce patients' symptoms.
- Brain scans showed an increase in dopamine cells in the brain and a decrease in what is known as off-time in patients.

Criticism of the researchers' optimism:

– Experts advise caution when interpreting the results due to possible inconsistent effects and potential placebo effect.
– It is not possible to directly observe the implanted brain cells.
- The mere fact that transplanted cells survived is not enough to confirm the actual benefit or effectiveness of the treatment.

Do you already have the Parkinson's Journal app?

The PJApp is available for a one-time fee of €2,89 and includes a lifetime subscription right.

And the best part is: The income from the sale of the App 50% will be donated to PingPongParkinson, 25% will go into a reserve around that Parkinson Journal at the turn of the year into a non-profit publishing company and only 25% serve to cover costs.

Especially for all those who are not yet ready to join a self-help group, we as a magazine would like to Window to Parkinson- be world. As victims, we know that Parkinson has become an unexpected companion in our lives. We want to show appreciation to these people and inform them with heart and mind. We want to show them that they are not alone and that there is hope and support.

By purchasing the app, you can support us on this journey.

You get the app at google play or by App Store
