This study observed that short-term administration of finasteride in male Wistar rats induced anxiety-like and depression-like behaviors, impaired spatial learning and memory, and reduced synaptic plasticity in the hippocampus, with a trend of increased corticosterone levels noted.

This study found that patients with trichodynia associated with androgenetic alopecia had significantly higher levels of substance P in both tissue and serum compared to healthy controls, suggesting a potential role for this neurotransmitter in the condition's pathogenesis.

In this study, significant associations were observed between specific genetic polymorphisms in BDNF and CRH-R1 and the occurrence of vitiligo, along with differing serum levels of neurotransmitters between vitiligo patients and healthy controls.

In this study, the authors explored the multifaceted connection between stress and stress-induced telogen effluvium, emphasizing how elevated cortisol levels and impaired microcirculation contribute to hair loss, along with potential interventions, including both medicinal and non-medicinal strategies like relaxation techniques and gentle care rituals.

This review evaluates controlled studies on Platelet-Rich Plasma for androgenetic alopecia treatment, reporting positive effects on hair growth and density but highlighting the need for standardized protocols.

Skin and hair cells release serotonin and histamine naturally, which could help improve skin health.

This review examines theories linking PCOS with psychiatric disorders, highlighting dietary interventions like probiotics and nutrients as possible improvements, but reports no new clinical findings and calls for more research.

This study found that microalgal extract from Botryococcus terribilis exhibited antidepressant-like effects in mice by regulating neuroinflammation and modulating neurotransmitter systems.

This review covers the neuroendocrine aspects of polycystic ovary syndrome, focusing on hormones and neurotransmitters like GnRH and kisspeptin, but does not report new clinical findings.

This article reviews the uses, mechanisms, and side effects of valproate in treating bipolar disorder, noting its first-line status for several manic conditions but also highlighting serious risks such as fetal abnormalities.

This review discusses the role of microglia in mediating prenatal androgen effects on the female brain, potentially contributing to PCOS development and neuroendocrine dysfunctions, but reports no new results.

The study discusses how stress can lead to telogen effluvium, a form of hair loss, by triggering hormonal imbalances and affecting microcirculation and hair follicle homeostasis. It highlights both medicinal and non-medicinal interventions, such as relaxation techniques and gentle care rituals, as potential treatment strategies.

This study found that in male rats, chronic finasteride treatment reduced allopregnanolone levels, which, upon drug withdrawal, correlated with increased pro-inflammatory cytokines and altered neurotransmitter levels.

This study suggests that P. orientalis leaf-derived EVs could offer anxiolytic, antidepressant, and sleep-inducing benefits by affecting neurotransmitter levels and reducing inflammation, particularly when administered intranasally.

This study found that ferulic acid significantly reduced seizure susceptibility and depression-like behaviors in a mouse model of catamenial epilepsy, likely by restoring hormone levels and neurotransmitter activity.

In this study with a mouse model of catamenial epilepsy, ferulic acid may effectively reduce seizure susceptibility and depression-like behavior by influencing hormone levels and neurotransmitter activity.

This study found that stimulation with certain neurotransmitters and hormones suggests the involvement of 5α-reduced neurosteroids in glial cell differentiation in rat C6 glioma cells.

This study found that curcumin administration improved cognitive and anxiety-related behaviors and neurochemical levels in HgCl₂ exposed mice pups, suggesting protective effects against heavy metal-induced neurotoxicity.

This study found that celery supplementation improved cognition and behavioral disorders in LPS-exposed mouse offspring by increasing levels of dopamine, acetylcholinesterase, and serotonin in the forebrain.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This study suggests that low level laser therapy may promote hair cell regeneration in rat cochlear explants following gentamicin-induced damage.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

This review discusses the potential of repeated low-level red-light therapy to inhibit myopia progression through metabolic effects, highlighting its molecular and cellular impact, but reports no new clinical results.

This study found that pediatric alopecia areata patients had significantly lower serum BDNF levels compared to healthy controls, which were associated with greater alopecia severity, higher depressive symptoms, and poorer quality of life.

This study found that elevated CgA levels in PCOS are associated with obesity, insulin resistance, and low-grade inflammation, suggesting CgA may be a novel biomarker for metabolic risk stratification in PCOS.

In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.
