Reduced Anxiety and Depression and Improved Mood in Older Adults Living in Care Homes After Participating in Chair Yoga.

Providing opportunities for older adults to engage in physical and mental activity is important to support healthy aging. The present preliminary study investigated the feasibility of accessible chair yoga for older adults in care homes. Chair yoga participants ( = 17) were assessed before and after attending twice weekly chair yoga sessions for 8 weeks, while control participants ( = 16) underwent the assessments only.

The selective 5-HT receptor agonist NLX-112 displays anxiolytic-like activity in mice.

Anxiety is amongst the commonest neuropsychiatric disorders, and there is a large body of evidence to suggest that abnormalities in serotonergic function are involved in its pathogenesis. Several studies have implicated 5-HT receptor activation in mitigating anxiety disorders, so this study investigated the acute effects of a highly selective, potent and efficacious 5-HT receptor full agonist, NLX-112 (a.k.

A general procedure to measure the pacing of body movements timed to music and metronome in younger and older adults.

Finger-tapping tasks are classically used to investigate sensorimotor synchronization in relation to neutral auditory cues, such as metronomes. However, music is more commonly associated with an entrained bodily response, such as toe tapping, or dancing. Here we report an experimental procedure that was designed to bridge the gap between timing and intervention studies by directly comparing the effects of metronome and musical cue types on motor timing abilities across the three naturalistic voluntary actions of finger tapping, toe tapping, and stepping on the spot as a simplified case of whole body movement.

Comparison of Spontaneous Motor Tempo during Finger Tapping, Toe Tapping and Stepping on the Spot in People with and without Parkinson's Disease.

Objective: Spontaneous motor tempo (SMT), observed in walking, tapping and clapping, tends to occur around 2 Hz. Initiating and controlling movement can be difficult for people with Parkinson's (PWP), but studies have not identified whether PWP differ from controls in SMT. For community-based interventions, e.

Music and Metronomes Differentially Impact Motor Timing in People with and without Parkinson's Disease: Effects of Slow, Medium, and Fast Tempi on Entrainment and Synchronization Performances in Finger Tapping, Toe Tapping, and Stepping on the Spot Tasks.

Introduction: Rhythmic auditory stimulation (RAS) has successfully helped regulate gait for people with Parkinson's disease. However, the way in which different auditory cues and types of movements affect entrainment, synchronization, and pacing stability has not been directly compared in different aged people with and without Parkinson's. Therefore, this study compared music and metronomes (cue types) in finger tapping, toe tapping, and stepping on the spot tasks to explore the potential of RAS training for general use.

Mood changes following social dance sessions in people with Parkinson's disease.

Dance interventions have physical benefits for the elderly, especially those with Parkinson's disease. This study assessed the psychological benefits of dance. A total of 37 participants, with either Parkinson's disease (n= 22) or age-matched controls (n= 15) completed mood questionnaires before and after a 10-week dance intervention.

Recombinant adeno-associated viral vector (rAAV) delivery of GDNF provides protection against 6-OHDA lesion in the common marmoset monkey (Callithrix jacchus).

Glial cell line-derived neurotrophic factor (GDNF) has shown potential as a treatment for Parkinson's disease. Recombinant adeno-associated viral vectors expressing the GDNF protein (rAAV-GDNF) have been used in rodent models of Parkinson's disease to promote functional regeneration after 6-OHDA lesions of the nigrostriatal system. The goal of the present study was to assess the anatomical and functional efficacy of rAAV-GDNF in the common marmoset monkey (Callithrix jacchus).

Sensorimotor deficits in a unilateral intrastriatal 6-OHDA partial lesion model of Parkinson's disease in marmoset monkeys.

Animal studies investigating the efficacy of neurotrophic factors as treatments for Parkinson's disease (PD) ideally require partial dopamine (DA) lesion models. The intrastriatal 6-hydroxydopamine (6-OHDA) lesion model may be suitable for this purpose. Although this model has been well characterized in rodents, it has not previously been used in monkeys.

Nigrostriatal alpha-synucleinopathy induced by viral vector-mediated overexpression of human alpha-synuclein: a new primate model of Parkinson's disease.

We used a high-titer recombinant adeno-associated virus (rAAV) vector to express WT or mutant human alpha-synuclein in the substantia nigra of adult marmosets. The alpha-synuclein protein was expressed in 90-95% of all nigral dopamine neurons and distributed by anterograde transport throughout their axonal and dendritic projections. The transduced neurons developed severe neuronal pathology, including alpha-synuclein-positive cytoplasmic inclusions and granular deposits; swollen, dystrophic, and fragmented neuritis; and shrunken and pyknotic, densely alpha-synuclein-positive perikarya.
