How to manage motor symptoms in patients with frontal parietal atrophy?

Management of Motor Symptoms in Frontal Parietal Atrophy

Pharmacological Management

For patients with frontal parietal atrophy, a combination of dopaminergic therapy and targeted symptom management is recommended as the first-line approach for motor symptoms.

• Dopaminergic medications such as levodopa/carbidopa should be used as the primary pharmacological treatment for parkinsonian motor symptoms that often accompany frontal parietal atrophy 1
• Rasagiline (1 mg daily) can be considered as an adjunct therapy when motor symptoms are not adequately controlled with levodopa alone, as it has been shown to reduce "OFF" time and improve motor function 1
• When using levodopa, administer at least 30 minutes before meals to avoid interactions with dietary proteins and maximize absorption 2
• Separate levodopa/carbidopa administration from calcium and iron supplements by at least 2 hours to minimize interference with absorption 2

Rehabilitation Approaches

Physical Rehabilitation

• Implement regular monitoring of motor function with standardized assessments to track progression and treatment response 3

• Focus on training that addresses specific motor deficits:

  • For tremor: Use strategies that superimpose alternative voluntary rhythms to gradually slow movement to complete rest 3
  • For dystonia: Encourage optimal postural alignment at rest and during functional activities 3
  • For functional limb weakness: Engage in tasks that promote normal movement patterns and even weight-bearing 3

• Inspiratory muscle training should be used to increase respiratory muscle strength and improve quality of life as an adjunct to standard physical therapy 3

Occupational Therapy Interventions

• Implement task-specific training that focuses on functional activities relevant to the patient's daily life 3
• Avoid excessive use of adaptive equipment in early stages as this may prevent improvement by interrupting normal automatic movement patterns 3
• If aids are necessary, they should be: (1) considered as short-term solutions; (2) issued with a minimalist approach; and (3) include a plan to progress toward independence 3
• Address vocational needs through workplace accommodations and graded return-to-work programs 3

Speech and Swallowing Management

• Perform standardized assessment of swallowing function before initiating oral nutrition, especially if dysphagia is present 3
• Consider fiberoptic endoscopic evaluation of swallowing (FEES) for accurate assessment of swallowing function 3
• Implement cognitive-behavioral strategies to address communication difficulties, including helping patients notice and challenge unhelpful thoughts about communication 3

Cognitive Rehabilitation

• Computer-based learning for attention functions and therapy aimed at improving cognition should be performed during rehabilitation 3
• Implement strategies that help patients notice and challenge unhelpful thoughts, incorporating principles from cognitive-behavioral therapy 3
• Use behavioral experiments to address fear and avoidance of specific activities 3

Nutritional Management

• Regular monitoring of nutritional status and vitamin levels is essential, with particular attention to:
  • Changes in body weight 3
  • Vitamin D, folic acid, and vitamin B12 levels 3
• Consider vitamin D supplementation as it may slow disease progression 3
• Monitor homocysteine levels in patients on levodopa therapy, as elevated levels may contribute to bone mineral density loss 3

Common Pitfalls and Management Challenges

• Avoid taking levodopa with high-protein meals as this reduces absorption and efficacy 2

• Be aware that weight loss is associated with disease progression and may require adjustment of medication dosages 3

• Recognize that patients with frontal parietal atrophy are at high risk for falls, particularly when motor symptoms overlap with atypical parkinsonian features 4

• Understand that motor symptoms may include a combination of:

  • Pseudoparesis of the hand that improves with visual attention 5
  • Variations in muscle tone (poikilotonia) 5
  • Limb kinetic and manipulatory apraxia 5
  • Abnormal anticipatory hand shaping when reaching for objects 5

• Monitor for progression of network dysfunction, as patients may show declining functional connectivity between subcortical-brainstem and parietal modules over time 6

Follow-up and Monitoring

• Conduct nutritional assessment at least yearly and whenever clinical conditions change 3
• Regularly assess for changes in motor symptoms, particularly for development of new parkinsonian features or functional decline 6
• Monitor for weight changes, as both weight loss and gain may occur during disease progression 3
