Thirty-seven untreated Parkinsonism patients showed significant positive correlations among decreased excretion of free dopamine, MMPI scores indicative of schizophrenic-like looseness of thinking, and the severity of all Parkinsonism signs except tremor. The data could indicate that abnormalities of dopamine metabolism may underlie both the motor and mental abnormalities of Parkinsonism.

Use of Robust Norming to Create a Sensitive Cognitive Summary Score in De Novo Parkinson's Disease: An Illustrative Example.

Article Synopsis
- Cognitive impairment is prevalent in Parkinson's disease (PD), but there's no agreement on the best neuropsychological tests to assess it; a Cognitive Summary Score (CSS) combines various tests into a single score for easier interpretation.
- This study aimed to see if a CSS, developed using strong norming methods, could identify early cognitive issues in untreated PD patients.
- Results show that PD patients performed worse than healthy controls across cognitive tests, especially in processing speed and verbal memory, and the CSS provided a more sensitive measure of cognitive decline than individual tests.

Cerebrotendinous xanthomatosis (CTX) is a rare but treatable inherited neurometabolic disorder that can lead to severe sequelae if left untreated. Chenodeoxycholic acid is a safe and effective treatment for CTX. Early diagnosis is essential to improve patient outcomes.

Parkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons in the substantia nigra that primarily affects movement control. Neuroinflammation plays a pivotal role in driving the disease's progression. The persistent inflammatory state in the brain exacerbates neuronal damage, creating a cycle that perpetuates the neurodegenerative process.

Background: Postural instability is considered a late complication of Parkinson's disease (PD). However, growing evidence shows that balance and gait problems may occur early in the disease.
Objective: To describe balance, gait, and falls/near falls in persons with newly diagnosed, untreated PD ("de novo"), and to compare this with persons with mild-moderate PD (Later PD).
