Four-Repeat Tauopathies: Current Management and Future Treatments

Area of Science:

• Neurodegenerative diseases
• Proteinopathies
• Tauopathies

Background:

• Four-repeat tauopathies are characterized by tau protein accumulation in the brain.
• These conditions manifest in diverse clinical syndromes, including progressive supranuclear palsy-Richardson's and corticobasal syndrome.
• Current treatments lack disease-modifying capabilities, necessitating symptomatic management.

Purpose of the Study:

• To review current symptomatic management strategies for common clinical symptoms in four-repeat tauopathies.
• To provide practical guidance for patient management, encompassing pharmacologic and nonpharmacologic approaches.
• To discuss the history and future of disease-modifying therapeutics and clinical trials.

Main Methods:

• Literature review of current approaches to symptomatic management.
• Focus on practical patient management strategies.
• Discussion of pharmacologic and nonpharmacologic interventions.

Main Results:

• Symptomatic management can improve quality of life for patients with four-repeat tauopathies.
• Management spans motor, sensory, cognitive, affective, autonomic, and behavioral domains.
• A comprehensive approach is required due to the wide range of symptoms.

Conclusions:

• Effective symptomatic management is crucial for improving patient quality of life in four-repeat tauopathies.
• Future research should focus on developing disease-modifying therapies and advancing clinical trials.
• Continued exploration of both pharmacologic and nonpharmacologic strategies is essential.
