Approximately 40% of the people affected by Parkinson’s are female. This number can vary across regions, but women still make up a large portion of the affected community.
That said, there is unfortunately very little research investigating women’s issues in Parkinson’s.
There are now efforts to correct this situation, however, and this change is being brought about by members of the affected community.
In today’s post, we will discuss some of what is known about how Parkinson’s affects women differently.
Why is today – the 8th March – called International women’s day? (backdated due to @#%$£&* technical issues!).
I don’t actually know. Perhaps because it’s politically correct that everyone should get their own day/month now?
The United Nations began celebrating International Women’s Day on the 8th March in 1975. But observation of the day date back to the early years of that century, and although the suffrage movement was occurring at the same time, International women’s day was very much a socialist idea.
And this shows itself in the timeline of events. For example, International Women’s Day was first observed on the 19th March, 1911 in Germany thanks to socialist activists like Luise Zietz, Käte Duncker and Clara Zetkin. But it wasn’t until 1918 that women were actually given the right to vote.
And remarkably, it was not until 1977 that the United Nations General Assembly invited its member states to proclaim the 8th March as the “UN Day for women’s rights and world peace”.
Interesting. But what does this have to do with Parkinson’s?
There is an imbalance in the amount of research being conducted on women in Parkinson’s.
In particular, there is a poverty of information regarding aspects of daily life for women living with Parkinson’s, especially those with young onset Parkinson’s.
What do you mean?
If you go to the medical research search engine Pubmed, and type in Parkinson’s and menopause, there are only 107 publications (dating back to 1971, 41 of them since 2010). To put that in context, there are over 105,000 research reports on Parkinson’s on the pubmed database. And most of them are not about menopause research, they simply mention the word menopause in their text. Similarly there are only 25 reports on parkinson’s and menstruation (and only 6 of them have been conducted since 2000!?!?).
Searching for male associated key words such as parkinson’s and prostate yeilds 177 publications (104 of which have been published since 2010 only).
And searching for Parkinson’s and male results in 43,000 reports, but searching for Parkinson’s and female only gives 36,000 reports.
So why the disparity?
Recently I wrote a post about research investigating an interesting compound called Epigallocatechin gallate (or EGCG – click here for that post). Several eagle-eyed readers, however, noted something interesting in the details of one of the research reports that was discussed in that post.
The study in question had used EGCG as a positive control for evaluating the ability of other compounds for their ability to inhibit the clustering of Parkinson’s-associated protein alpha synuclein.
But there was also a second positive control used in that study.
It is called baicalein.
In today’s post, we will discuss what baicalein is and what research has been done on it in the context of Parkinson’s.

Once upon a thyme, in a far away land, there was a mysterious little flowering plant.
The “far away land” was the southern parts of eastern Siberia.
And the flowering plant is Scutellaria baicalensis – which is more commonly referred to as Baikal skullcap.
What is Baikal skullcap?
Baikal skullcap is a perennial herb that is indigenous to Southern Siberia, China and Korea. For centuries, traditional Chinese medicine has used the dried roots – which is called huángqín (Chinese: 黄芩 or golden root) – for a variety of ailments.

The plant grows to between 1-4 feet in height, with lance head-shaped leaves and blue-purple flowers. Baikal skullcap belongs to the same family of flowering plants (Lamiaceae) as thyme, basil, mint and rosemary.
For traditional Chinese medicinal use, the roots are usually collected in spring or autumn once the plant is more than 3-4 years old. They are dried and then used to treat hypertension, to reduce “fire and dampness”, and to treat prostate & breast cancers.
And one of the key constituents of Baikal skullcap (and huángqín) is a compound called baicalein.
