Cardinal motor features of Parkinson's disease (PD) include bradykinesia, rest tremor, and rigidity, which appear in the early stages of the disease and largely depend on dopaminergic nigrostriatal denervation. Intermediate and advanced PD stages are characterized by motor fluctuations and dyskinesia, which depend on complex mechanisms secondary to severe nigrostriatal loss and to the problems related to oral levodopa absorption, and motor and nonmotor symptoms and signs that are secondary to marked dopaminergic loss and multisystem neurodegeneration with damage to nondopaminergic pathways. Nondopaminergic dysfunction results in motor problems, including posture, balance and gait disturbances, and fatigue, and nonmotor problems, encompassing depression, apathy, cognitive impairment, sleep disturbances, pain, and autonomic dysfunction. There are a number of symptomatic drugs for PD motor signs, but the pharmacological resources for nonmotor signs and symptoms are limited, and rehabilitation may contribute to their treatment. The present review will focus on classical notions and recent insights into the neuropathology, neuropharmacology, and neurophysiology of motor dysfunction of PD.
"Howard is a super athlete. He works out regularly and plays several sports. He never eats vegetables and rarely eats fruit. He pulled a hamstring last week playing soccer" is the one among the following that <span>is most likely to experience stress. He is an athlete, but he has to stay away from games and this creates stress in his mind. For the other three options, there is no chance of stress. The correct option among all the options that are given in the question is the second option or option "B". </span>

Tricyclic antidepressant (TCAs) class is most closely linked with anticholinergic side effects.
Amitriptyline, amoxapine, clomipramine and protriptyline are Tricyclic antidepressants (TCAs) that are used to treat chronic pain. Amitriptyline and nortriptyline among these medications provide the most reassuring safety information during pregnancy and breastfeeding.
In vitro and in vivo, TCAs are powerful inhibitors of norepinephrine and/or serotonin reuptake. In addition, several TCAs are known to block sodium, calcium, alpha-1 adrenoceptors, histamine (H1) receptors, and muscarinic cholinergic receptors. Thought to be responsible for their unfavourable anticholinergic, antihistaminergic, and cardiotoxic side effects rather than their antidepressant effects, these neurotransmitter receptor actions.
