a number of us presented PD symptoms from early in childhood.

I read somewhere that PD symptoms are evident when 80% of neurons are not functioning and this typically takes around 10 years elapsed.

I believe the brain regenerates upto around 25 years of age.
Really simplistic view, lets assume this regeneration means PD cannot occur until 26 years old.
Taking the 10 year incubation period this means the earliest PD presents itself is in the mid 30s.

However John was dx'ed at 50 years old and I was dx'ed at 40 years of age.

Our stories suggest we had PD early in our lives.

So what was PD doing in the years between our childhood and the first clinical presentation of symptoms.

I would be interested to get the view of the large PD charities as to whether they believe PD signs can exist in early childhood and if so, do they have any idea what is the process by which it remains dormant until later life. I will chase up PDS UK and MJFF and get back to you.

I have a personal interest in this as my granddaughter is displaying little habits and tics. This may be nothing but then again ...

Regards,
Neil.
