Presentation
Atypical PKAN usually presents around the age of 14 years, has less severe extrapyramidal impairment, slow progression, heterogeneous presentation, and may manifest neuropsychiatric symptoms in about 30% of cases. 2 Early stages may present with depression [demneuropsy.com.br]
Atypical features may also be present, such as depression, dementia, and hallucinations. [athenadiagnostics.com]
Lewy bodies, the key pathological hallmark of PD, are not present in vascular parkinsonism. [apdaparkinson.org]
Compelling vignettes covering the entire phenomenology of movement disorders are presented succinctly but descriptively to walk the reader through the diagnostic processómuch like being in the examining room with a master clinician. [books.google.com]

Treatment
Traditionally amantadine is used at the beginning of Parkinson Disease (PD) treatment in the early stages of the disease, as a modest antiparkinsonian symptomatic treatment. [clinicaltrials.gov]
What treatments exist for dystonia? Dystonia and Parkinson's share common forms of treatment. [michaeljfox.org]

The use of this class of drug earlier in the treatment cycle represents current theory, suggesting that many of the late treatment complications associated with PD treatment are a result of the short half-life of levodopa. [clevelandclinicmeded.com]
Therapy and Treatment When it comes to medical treatment, people with YOPD have a significantly greater risk of developing the following: Dyskinesias or involuntary movements (most commonly dystonia) as a side effect of carbidopa A medication used together [parkinson.org]

Equally critical, PD must be distinguished from less common forms of parkinsonism because prognosis and treatment may differ. [mhmedical.com]

Furthermore, the symptomatic therapies used today are often effective irrespective of etiology. [what-when-how.com]
This disruption can take one of many forms, and depending on the etiology, other brain structures may be involved. [mhmedical.com]
