Are hallucinations and delusions in Parkinson's disease due to medications or an intrinsic part of the disease?

This is what we tried to answer by going back in time to case notes prior to the use of dopaminergic therapies.

Let's explain...

If you see a patient with catatonia, how do you know what's causing it?

Is it due to a psychiatric condition or a neurological disorder?

That's the Q we asked in this BIG meta-analysis of EEG findings in catatonia in @eClinicalMed.

Key points in 🧵: Specifically, we wanted to know whether a normal clinical EEG helps you in making this distinction between 'psychiatric' and 'medical' causes of catatonia.

Interesting finding about the genetics of periodic catatonia over 3 centuries that I've only just managed to piece together: a 🧵.

(Others probably got here before me, but it's taken me a while...)

Firstly, periodic catatonia... Periodic catatonia was described in 1894 and acknowledged subsequently by Bleuler and Kraepelin. It consists of recurrent episodes of catatonia, arguably with alternating hyperkinetic and hypokinetic periods.

I listen to quite a lot of podcasts to learn and stay up-to-date in psychiatry.

Here's a 🧵with some of the best:

1. BRAINCAST by @maudsleylearn: Fantastic range of topics with a centre of gravity around neuropsychiatry.

Sadly stopped producing new episodes, but maybe we can persuade @Pospo to get it going again. Listen to the complete back catalogue.
