So... I was looking at this paper: The Effect of Intranasal Oxytocin in Patients With Functional Motor Symptoms: A Preliminary Open-Label Case Series sci-hub.ru/10.1097/JCP.0000...
And I started looking to see what "Functional Motor Symptoms" were and they turned out to be a "Functional neurologic disorder": Functional neurologic disorder (FND), also known as conversion disorder and functional neurologic symptom disorder, refers to a group of common neurological movement disorders caused by an abnormality in how the brain functions. FND is not caused by another disorder and there is no significant structural damage in the brain. The exact cause of FND is unknown. FND was thought to be a “conversion disorder” by Sigmund Freud because he believed a psychological disorder converted into a neurological one.
Someone with FND can function normally, they just can't at that moment. Their brain is unable to send and receive signals properly and there is a disconnection in the function of the lobes and emotional processing. Memory, concentration, cognition, and the processing of sensations also can be affected.
Functional movement disorder (FND) affects movement of the body. Symptoms may include:
Leg and arm weakness or paralysis
Tremor
Sudden, brief involuntary twitching or jerking of a muscle or group of muscles (myoclonus)
Involuntary muscle contractions that cause slow repetitive movements or abnormal postures (dystonia)
Problems with walking motion (gait), posture, or balance
Spasms and contractures (in which the tendons become fixed in awkward or uncomfortable positions)
Muscle stiffness
Tics
Symptoms that affect other brain functions may include:
Speech difficulties, such as sudden onset of stuttering or trouble speaking
Problems with seeing or hearing
Pain (including chronic migraine)
Extreme slowness and fatigue
Numbness or inability to sense touch
So we have a Functional neurologic disorder that is not organic and per the internet might be able to be cured.
Now it get more odd: "Patients with Parkinson disease are prone to functional neurological disorders" ncbi.nlm.nih.gov/pmc/articl...
"Until recently the management of Parkinson disease focused almost entirely on the triad of bradykinesia, rigidity and tremor. It then became apparent that there are many non-motor features as well, and management of these is often as important as the motor symptoms. The work of Onofrj et al. first reported that functional symptoms are also frequent in Parkinson disease.1 In a large study of 488 patients with Parkinson disease, 7.5% had some “somatoform disorders,” both motor and non-motor in type. They also noted that these symptoms could precede the motor and non-motor symptoms. The paper by Wissel et al. on p. xxx describes details of functional symptoms in 53 patients with Parkinson disease which should help in diagnosing them."
[Somatoform disorder, also known as somatic symptom disorder (SSD) or psychosomatic disorder, is a mental health condition that causes an individual to experience physical bodily symptoms in response to psychological distress.]
So what is my point?
A) It seems like a person could have a number of PD like symptoms without having PD.
B) It seems that a person could have PD, and have symptoms that look like PD symptoms that are not part of the PD.
For instance, I have had myoclonus for over 10 years. Myoclonus does not seem to be a symptom of PD (I have not been diagnosed with PD). I just kind of thought the random movements were a sign of PD.
To circle the rest of the way around, this article The Effect of Intranasal Oxytocin in Patients With Functional Motor Symptoms: A Preliminary Open-Label Case Series sci-hub.ru/10.1097/JCP.0000... says intranasal oxytocin might help with Functional neurologic disorders. I have been digging into intranasal oxytocin for a few days now.
