Understanding Parkinson’s Plus Syndromes: Beyond Parkinson’s Disease

Parkinson’s disease (PD) is a well-known neurological condition characterized by motor symptoms such as tremors, bradykinesia (slowness of movement), and rigidity. However, there are other neurological disorders, collectively known as Parkinson’s Plus syndromes, that share some similarities with PD but have distinct clinical features and progression. In this blog post, we’ll explore Parkinson’s Plus syndromes, shedding light on their characteristics, diagnosis, and management.

What are Parkinson’s Plus Syndromes?

Parkinson’s Plus syndromes, also referred to as atypical parkinsonism or parkinsonian disorders, are a group of neurodegenerative conditions that share overlapping features with Parkinson’s disease but exhibit additional symptoms and distinct pathology. Unlike PD, which primarily affects the dopamine-producing neurons in the substantia nigra region of the brain, Parkinson’s Plus syndromes involve more widespread degeneration of brain cells and often have a more rapid progression.

Types of Parkinson’s Plus Syndromes:

  • Multiple System Atrophy (MSA):
    • MSA is characterized by a combination of parkinsonian motor symptoms, autonomic dysfunction, and varying degrees of cerebellar or pyramidal features. The hallmark pathology of MSA is the accumulation of abnormal alpha-synuclein protein in glial cells, leading to degeneration of multiple brain regions, including the basal ganglia, cerebellum, and autonomic centers.
  • Progressive Supranuclear Palsy (PSP):
    • PSP is characterized by progressive impairment of balance and gait, along with oculomotor dysfunction (e.g., vertical gaze palsy, difficulty with eye movements). Pathologically, PSP is associated with the accumulation of tau protein in neurons and glial cells, leading to degeneration of the brainstem, basal ganglia, and cerebral cortex.
  • Corticobasal Syndrome (CBS):
    • CBS is characterized by asymmetric rigidity, bradykinesia, apraxia (difficulty with skilled movements), and cortical sensory deficits. Pathologically, CBS is associated with tau protein deposition in neurons and glial cells, primarily affecting the cerebral cortex and basal ganglia.

Diagnosis and Management:

Diagnosing Parkinson’s Plus syndromes can be challenging due to their overlapping symptoms with Parkinson’s disease and other neurodegenerative disorders. A comprehensive evaluation by a neurologist, including a detailed medical history, neurological examination, and neuroimaging studies (e.g., MRI, PET scans), is essential for accurate diagnosis.

Management of Parkinson’s Plus syndromes focuses on symptom management and supportive care, as there are currently no disease-modifying treatments available. Medications may be prescribed to alleviate motor symptoms, while physical therapy, occupational therapy, and speech therapy can help maintain mobility, independence, and quality of life. Close monitoring and regular follow-ups with a neurologist are crucial for adjusting treatment strategies and addressing evolving symptoms.


Parkinson’s Plus syndromes represent a group of complex and heterogeneous neurodegenerative disorders that pose unique challenges for diagnosis and management. By increasing awareness and understanding of these conditions, we can better support individuals affected by Parkinson’s Plus syndromes and their caregivers. At CNS, our experienced neurology team is dedicated to providing comprehensive care and support to patients with Parkinson’s Plus syndromes, empowering them to navigate their journey with compassion, expertise, and dignity.
