Little is known about the neurological control of human sexual behavior. Investigating and measuring this behavior by using quantitative and objective methods is difficult. Insights from lesion studies contribute to analyze the effects of neurological disorders on human sexual behavior. In this chapter, we focus on frontal lobe lesions, brain injuries, epilepsia, dementia, and Parkinson disease to describe human sexual behavior disorders, in order to highlight cortical and subcortical brain regions and neural networks involved in human sexual behavior...

The nocebo effect, the inverse of the placebo effect, is a well-established phenomenon, yet under-appreciated. It refers to nonpharmacological, harmful, or undesirable effects occurring after active or inactive therapy. The frequency of adverse events can dramatically increase by informing patients about the possible side effects of the treatment, and by negative expectations on the part of the patient. Patients who were told that they might experience sexual side effects after treatment with β-blocker drugs reported these symptoms between three and four times more often than patients in a control group who were not informed about these symptoms...

Mucuna pruriens is a well-known legume for the itching attributes of the trichome and a valuable medicinal herb that is used for the treatment of Parkinson's disease, sexual debilities, etc. Its cultivation was deprived due to its itching behavior. The wild genotype of M. pruriens have the largest trichome length (2015 ± 29 μm) compared to other genotype and mutants. The white-seeded variety of M. pruriens was found to be the most suitable for large-scale cultivation due to the small trichome size and less trichome density on the pod...

Parkinson's disease (PD) is the second most frequent age-related neurodegenerative disorder. Sex is an important factor in the development of PD, as reflected by the fact that it is more common in men than in women by an approximate ratio of 2:1. Our hypothesis is that differences in PD among men and women are highly determined by sex-dependent differences in the nigrostriatal dopaminergic system, which arise from environmental, hormonal and genetic influences. Sex hormones, specifically estrogens, influence PD pathogenesis and might play an important role in PD differences between men and women...

BACKGROUND: Pelvic symptoms are distressing symptoms experienced by patients with Friedreich's Ataxia (FRDA). The aim of this study was to describe the prevalence of lower urinary tract symptoms (LUTS), bowel and sexual symptoms in FRDA. METHODS: Questionnaire scores measuring LUTS, bowel and sexual symptoms were analysed with descriptive statistics as a cohort and as subgroups (Early/Late-onset and Early/Late-stage FRDA) They were also correlated with validated measures of disease severity including those of ataxia severity, non-ataxic symptoms and activities of daily living...

Paradoxical kinesia refers to a sudden transient ability of akinetic patients to perform motor tasks they are otherwise unable to perform. The mechanisms underlying this phenomenon are unknown due a paucity of valid animal models that faithfully reproduce paradoxical kinesia. Here, in a first experiment, we present a new method to study paradoxical kinesia by "awakening" cataleptic rats through presenting appetitive 50-kHz ultrasonic vocalizations (USV), which are typical for social situations with positive valence, like juvenile play or sexual encounters ("rat laughter")...

While awareness of institutional child sexual abuse has grown in recent years, there remains limited understanding of its occurrence and outcomes as a distinct form of abuse. Drawing on research commissioned by the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, this article presents a rapid review of available evidence on the impacts of institutional abuse on victim/survivors. Literature searches identified 75 sources spanning international peer reviewed work and reports to Government that document or quantify the impacts of mostly historical child sexual abuse occurring in religious, educational, sporting and residential or out-of-home care settings...

Non-motor symptoms of Parkinson's disease have a significant impact on quality of life. Despite this, many non-motor symptoms remain unreported by patients and consequently untreated. This study explored barriers to help-seeking using two theoretical frameworks, the Common Sense Model of illness perception and Theoretical Domains Framework. A total of 20 participants completed semi-structured interviews to explore symptom beliefs and help-seeking behaviour. Uncertainty about the relationship of non-motor symptoms to Parkinson's disease and lack of clarity around treatments were common...

Sexual dysfunctions (SDs) are one of the most neglected nonmotor symptoms in Parkinson's disease (PD). A number of reasons including social and cultural factors might explain, at least partially, why SD is still one of the most underrecognized aspects of the condition after 200 years since the very first description by James Parkinson. SD has not been extensively investigated, however, a number of studies have shown a high prevalence of decreased libido, orgasmic dysfunction in both men and women with PD, and erectile dysfunction in male subjects...

Pump-based Parkinson (PD) therapies, including subcutaneous apomorphine infusion (CSA) and levodopa-carbidopa intestinal gel (LCIG), presently constitute the most effective pharmacological treatments available for advanced PD. These therapies are based on a more constant delivery of the dopaminergic drug resulting in a more continuous dopaminergic stimulation and a more stable treatment effect. This can be detected as reduction of time in off, reduction of dyskinesia frequency and severity, as well as increase of time in on without troublesome dyskinesias...

Delays in disclosing and reporting child sexual abuse to the police are common, particularly among males and those who have been abused by clergy and others in a position of trust. This study, commissioned by the Royal Commission into Institutional Responses to Child Sexual Abuse, examined the patterns of timely and delayed reporting of sexual offences against children, and the likelihood of legal action commencing. De-identified unit record data for all sexual offences against children reported to the police over 20 years were obtained from official crime statistics agencies in two Australian states...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...

BACKGROUND: Parkinson's Disease Nurse Specialists (PDNS) play an important role in the care for patients with Parkinson's disease (PD) and their caregivers. Until now, there were no nursing guidelines in PD, and interventions were based solely on daily clinical practice because there is no evidence to support the merits of nursing interventions. Consequently, there is little uniformity in current care delivery. OBJECTIVE: Developing a guideline for PDNS. METHODS: We developed a guideline based on a questionnaire among PDNS and a literature review, supplemented with expert opinion plus the input of patients and caregivers...

Sexual dimorphism has been described in various aspects of physiological and pathophysiological processes involving dopaminergic signaling. This might account for the different disease characteristics in men and women in e.g. Parkinson's disease or ADHD. A better understanding might contribute to the future individualization of therapy. We examined spontaneous wheel running activity of male and female mice, homo- and heterozygote for dopamine D3 receptor deficiency (D3R -/- and D3R+/-), and compared them to wild type controls...

The role of sex in biomedical studies has often been overlooked, despite evidence of sexually dimorphic effects in some biological studies. Here, we used high-throughput phenotype data from 14,250 wildtype and 40,192 mutant mice (representing 2,186 knockout lines), analysed for up to 234 traits, and found a large proportion of mammalian traits both in wildtype and mutants are influenced by sex. This result has implications for interpreting disease phenotypes in animal models and humans.

BACKGROUND: One in 5 recently deployed US women veterans report overactive bladder symptoms. Mental health conditions such as depression and anxiety commonly co-occur in women with overactive bladder, but temporal relationships between these outcomes have not been well studied, and the mechanism behind this association is unknown. The Women Veterans Urinary Health Study, a nationwide longitudinal study in recently deployed women veterans, was designed to better understand relationships between overactive bladder and mental health conditions...

Apart from the typical motor symptoms, Parkinson's disease is characterized by a wide range of different non-motor symptoms, which are highly prevalent in all stages of the disease and have an incisive influence on quality of life. Moreover, their treatment continues to be challenging. In this review, we critically summarize the evidence for the impact of dopaminergic therapies on non-motor symptoms in Parkinson's disease. We performed a PubMed search to identify relevant clinical studies that investigated the response of non-motor symptoms to dopaminergic therapy...

BACKGROUND: Major depressive disorder (MDD) is a severe mental illness that affects more than 350 million people worldwide. However, the molecular mechanisms of depression are currently unclear. Studies suggest that Drosophila and humans have similar depression-like symptoms under pressure. In this research, we choose Drosophila melanogaster as the animal model to explore the molecular mechanisms that trigger depression. RESULTS: We found that feeding D. melanogaster with the medium containing Levodopa or Chlorpromazine could induce depression-like phenotypes in both behavioral and biochemical biomarkers, including significantly decreased food intake, mating frequency, serotonin (5-HT) concentration, and increased malondialdehyde (MDA) concentration as well as reduced activity of superoxide dismutase (SOD)...
