или "формы БП, при которых нарушения, связанные с дефицитом дофамина, не являются преобладающими"

Пропустил вопрос, к сожалению.

Одной из основных проблем при БП является дефицит дофамина. Но вот видимо сейчас начинают понимать, что есть другие формы БП, при которых нарушения опосредуются другими механизмами, нежели дефицит дофамина, либо при которых на первый план выходят немоторные симптомы.

There are a lot of disorders related to neurotransmitter dysfunction, including depression, anxiety, insomnia, migraines, trichotillomania, OCD, RLS and Parkinson’s disease, among others. The vast majority of people with these conditions (aside from RLS and Parkinson’s) are serotonin dominant, which means that these people normally require much more support for serotonin than the catecholamines (dopamine, norepinephrine and epinephrine) in order to optimize neurotransmitter function. On the opposite end of the spectrum are those people that are dopamine dominant; this includes people with RLS and Parkinson’s Disease. In addition, there is a small group of people with conditions that are typically serotonin dominant (roughly between 6-12%) that actually end up needing significant dopamine support (i.e, they are dopamine dominant). The only way to determine this is via specialized urine testing. To make matters more complicated, it turns out that there is a third group of people that need significant support for both the serotonin and catecholamine systems; these people are typically labeled “hybrids”.

и вот здесь в целом:

All of the diseases where dopamine is the dominant problem require the same approach, “dopamine dominant.” Parkinson’s disease is the prototype disease for understanding management of dopamine dominant problems.
