Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms due to the loss of dopamine-producing neurons and the presence of Lewy bodies in the brain. While current treatments such as dopamine replacement with levodopa and deep brain stimulation mainly manage symptoms and do not stop disease progression, recent advancements in nanomedicine provide promising new therapy options. These include drug-loaded nanocarriers that improve drug delivery to the brain, enhancing effectiveness and reducing side effects. This review explores novel nanomedical approaches like solid lipid nanocarriers (SLNs), which could improve drug profiles and decrease the adverse effects seen with traditional PD treatments. Additionally, it discusses the challenge of crossing the blood–brain barrier, which is crucial for treating central nervous system disorders, and how nanocarriers facilitate targeted brain delivery. Despite these advancements, the review emphasizes more research into the safety and long-term impacts of nanomedicine in PD, highlighting the challenge of moving these treatments from lab to clinical use.
