No New Relevant Treatment Options for L-DOPA-Induced Dyskinesia from a Clinician's Point of View.
Review in Neurology international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe term dyskinesia describes involuntary movements of the face, body and extremities. Frequently, they appear following and in relation with prior oral long-lasting and high-dose levodopa therapy in Parkinson's disease patients. Onset of these motion sequences causes patient distress and caregiver embarrassment with declined quality of life. Continuity of nigrostriatal postsynaptic dopamine receptor stimulation delays occurrence of dyskinesia. A pulsatile pattern with temporary too high dopamine receptor excitation promotes manifestation of dyskinesia.
methodsThis narrative review describes past pharmacologic approaches for therapy of dyskinesia, such as the principle of continuous dopamine receptor stimulation. DISCUSSION AND
conclusionsNovel concepts were tested. They influenced neurotransmission of serotonin and altered stimulation of dopamine receptor subtypes. The translation of successful experimental research outcomes into valuable clinical trial results with consecutive approval of drugs with a new mode of action under the indication "antidyskinetic" repeatedly failed. An exception is the open-channel blocker of the N-methyl-D-aspartate receptor and dopamine reuptake inhibitor amantadine with its moderate dyskinesia-reducing effects, particularly in its extended-release formulation. This antiviral compound also improves impaired motor behavior and reduces "OFF" intervals. Therefore, amantadine is currently experiencing a certain resurgence in regions where its extended-release formulations are marketed for therapy of levodopa-induced dyskinesia.
