This report highlights a case where a woman's use of the dopamine agonist pramipexole for Parkinson's disease was associated with hair loss, which improved after discontinuing the drug.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This case report describes two postmenopausal women with Parkinson's disease who experienced reversible hair loss after using the dopamine agonists pramipexole and ropinirole.

This study found that copper injections increased dopamine-β-hydroxylase activity in the brains of mottled mice, an animal model for Menkes' syndrome.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

A specific gene variant is linked to heart disease, increased heart muscle, curly hair, and thick skin on palms and soles.

This study suggests that a newly discovered protein, AMY117, found in Alzheimer's disease brain lesions may be crucial in the disease's development and progression.

This study identified a heterozygous de novo mutation in the ODC1 gene causing a new disorder characterized by overgrowth and developmental delay, and suggests that DFMO treatment may help manage elevated ODC activity and putrescine levels.

In this study, pregnenolone was found to dose-dependently reduce L-DOPA-induced dyskinesias in a rat model of Parkinson's disease, suggesting its potential as a therapeutic target for these dyskinesias.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This source explains that Equine Cushing’s disease, or PPID, in horses is due to the degeneration of brain cells producing dopamine, leading to elevated cortisol levels and characteristic symptoms; it outlines diagnosis methods and emphasizes life-long pergolide treatment to manage the condition.

This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

A woman's unique dementia was misdiagnosed, a genetic mutation increases Parkinson's risk with age, and finasteride may help with Tourette syndrome.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

In this study, researchers developed a novel delivery system using hyaluronic acid gels to encapsulate Huperzine A for Alzheimer's treatment, achieving extended release over 20 days and significantly improving pathology and behavior in mice, including enhanced memory and reduced neuroinflammation.

In this paper, three APS patients were followed over time, showing that the diagnosis and course of autoimmune polyglandular syndrome can evolve, highlighting the need for careful monitoring and potential re-evaluation.

Finasteride reduces certain behaviors caused by D1-like receptor agonists but not by D2-like receptor agonists in mice.

This study found that finasteride significantly reduced levodopa-induced dyskinesia in both male and female rats without diminishing l-DOPA's motor benefits, indicating potential for clinical trials in Parkinson's patients.

This study found that polyamidoamine dendrimers can permeate skin's current conducting pores and alter the magnitude and direction of electroosmotic flow, affecting drug flux during iontophoresis.

This report describes a neurometabolic disorder linked to gain-of-function variants in the ODC1 gene, characterized by developmental delay, ectodermal abnormalities, and notable facial and neuroimaging features.

Antisense oligonucleotides show promise for treating Myotonic Dystrophy type I.

This study found that distinct neurons in the nucleus accumbens lateral shell regulate scratching behavior differently; D1R neurons promote scratching while D2R neurons help stop it, with elevated dopamine levels during chronic itch potentially enhancing persistent scratching.

This source explains that unlike genetic hormonal alopecia, alopecia areata is associated with inflammatory factors and may also involve psychological and genetic contributions.

In this study, 27.9% of Parkinson's disease patients reported hair loss, with a higher incidence linked to a daily levodopa-equivalent dose over 448 mg, suggesting an association between dopaminergic medication use and hair loss complaints.

Finasteride may help improve certain brain function issues linked to dopamine.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.
