The primary objectives of this study include:

- Characterize neuroplastic changes associated with creative engagement
Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder characterized by the accumulation of abnormal tau protein in various brain regions. It belongs to a group of conditions known as atypical parkinsonian syndromes or 4R-tauopathies[@sterman2020].
PSP affects approximately 6-9 per 100,000 individuals, with a typical onset between 50-70 years of age. The disease progresses relentlessly, with most patients becoming severely disabled within 5-10 years of symptom onset.
Core Clinical Features:
- Vertical supranuclear gaze palsy: Difficulty with downward eye movements, a hallmark finding
- Postural instability: Frequent falls, typically backward
- Parkinsonism: Bradykinesia, axial rigidity
- Cognitive dysfunction: Frontal executive impairment, apathy
- Speech and swallowing difficulties: Dysarthria and dysphagia
Subtypes:

The neurodegenerative nature of PSP presents unique challenges for therapeutic interventions. While disease-modifying treatments remain under development, supportive and symptomatic therapies play a critical role in maintaining quality of life[@schott2022].
Traditional pharmacological approaches in PSP offer limited benefit:
- Levodopa provides modest improvement in some patients, particularly PSP-P subtype
- No disease-modifying drugs exist for PSP
- Symptomatic treatments target individual symptoms (e.g., botulinum for dystonia)
This limitation has driven interest in non-pharmacological approaches that address multiple domains of function simultaneously.
Art therapy is a form of psychotherapy that uses creative expression to promote emotional, cognitive, and social well-being. It has been applied successfully in various neurological conditions, including Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders[@farris2019][@cue2019].
Mechanisms of Benefit:
- Cognitive Stimulation: Engagement in creative activities activates multiple brain networks, including visual, motor, and executive regions
- Emotional Expression: Art provides a non-verbal medium for expressing complex emotions, particularly valuable in conditions affecting communication
- Motor Rehabilitation: Fine motor activities in art-making may help maintain hand function and coordination
- Social Engagement: Group art sessions provide opportunities for social interaction and reduce isolation
- Psychological Well-being: Creative engagement reduces anxiety, depression, and improves self-esteem
Research has demonstrated that art therapy can improve behavioral and psychological symptoms of dementia[@cue2019], enhance quality of life in Parkinson's disease[@farris2019], and reduce caregiver burden[@chancellor2022].
¶ Neuroplasticity and Creative Engagement
Art therapy is thought to work through multiple neuroplastic mechanisms[@kim2021]:
Structural Changes:
- Increased gray matter in prefrontal cortex
- Enhanced connectivity in default mode network
- Preservation of motor cortex volume
Functional Changes:
- Activated visual creativity networks
- Enhanced motor planning and execution
- Improved emotional regulation circuits
PSP presents specific challenges that art therapy may address:
- Communication Difficulties: PSP progressively impairs speech and language. Art provides alternative communication channels
- Cognitive Impairment: Frontotemporal dysfunction in PSP affects executive function. Art activities can provide structured cognitive engagement
- Motor Limitations: While fine motor control declines, art activities can be adapted to individual capabilities
- Emotional Impact: Depression and anxiety are common in PSP. Creative expression offers emotional release
- Caregiver Burden: Caregivers experience high levels of stress. Art therapy can provide respite and meaningful engagement for patients
Multiple studies support art therapy benefits in neurodegenerative diseases:
Parkinson's Disease:
- Art therapy improves quality of life scores and reduces motor symptoms
- Creative activities enhance dopamine-mediated reward pathways
- Group art sessions reduce social isolation[@mahoney2020][@takahashi2020]
Dementia:
- Cochrane review supports art therapy for behavioral symptoms
- Reduces agitation and improves emotional well-being
- Provides meaningful engagement in advanced stages[@hackett2002]
Atypical Parkinsonism:
- Non-pharmacological interventions show promise in multiple studies
- Creative arts address both motor and non-motor symptoms
- Adapted activities accommodate progressive limitations[@druter2019]
