Widespread Monoaminergic Dysregulation of Both Motor and Non-Motor Circuits in Parkinsonism and Dyskinesia.

A substantial increase in DA levels in these regions, paralleled by a decrease in serotonin concentrations were related with dyskinesia severity, demonstrating that major changes in monoamine release also occur in nonmotor regions.

A meta-analysis of the response to chronic l-dopa in patients with schizophrenia: therapeutic and heuristic implications

In patients already on antipsychotic drugs, the addition of l-dopa can be beneficial, and Dopamine agonists merit further consideration as adjuncts to antipsychotics drugs in the treatment of schizophrenia.

Neurotoxins and Drugs for the Treatment of Parkinson's Disease. Part I: Neurotoxins, Levodopa, and Agents Influencing Dopamine Metabolism (A Review)

This is the first part of a review devoted to xenobiotics involved in the pathogenesis of Parkinson's disease (PD) and to modern antiparkinsonian agents. Experimental and epidemiological evidence

Somatic Delivery of Catecholamines in the Striatum Attenuate Parkinsonian Symptoms and Widen the Therapeutic Window of Oral Sinemet in Rats

It is confirmed that parkinsonian symptoms can be quantified in rats with severe dopamine depletions, and the validity and clinical relevance of these measures are supported by the fact that the clinical gold standard treatment, oral sinemet, attenuates these parkinsonia symptoms.

Elevated dopamine in the medial prefrontal cortex suppresses cocaine seeking via D1 receptor overstimulation

Results suggest that stimulation of D1 receptors in the dorsal mPFC plays a crucial role in cocaine‐induced reinstatement of cocaine seeking, whereas the suppressant effect of DBH inhibitors and L‐DOPA on drug‐ induced reinstatement is mediated by a supra‐maximal stimulation ofD1 receptors leading to their inactivation.



Dopamine receptor changes in response to prolonged treatment with L-dopa.

The biochemical changes of DA-D1 receptors associated with adenylate cyclase seem to be correlated with the enhanced behavioural responses to apomorphine and could be a consequence of a decreased opiate inhibitory tone on the enzyme.

Dopamine Agonists in Parkinson’s Disease

ABSTRACT Dopamine agonists have yielded two important advances to our understanding of the basal ganglia – they have facilitated the subdivision of different classes of dopamine receptors, and they

An important stimulatory role for DA in regulation of HPA activity is suggested, and a role for both DA and 5-HT in the adrenocortical stimulation by cocaine is suggested.

New data suggest that there may be regionally restricted changes in the function of the mesotclencephalic dopamine system, and that these changes may be in opposite directions.
