Childhood Dementia: A Collective Clinical Approach to Advance Therapeutic Development and Care

Area of Science:

• Pediatric Neurology
• Neurodegenerative Diseases
• Rare Diseases

Background:

• Childhood dementias are over 100 rare pediatric conditions characterized by progressive neurocognitive decline.
• These conditions lead to skill loss, shortened life expectancy, and profound family impact, with limited disease-modifying therapies available.
• Current research often focuses on individual disorders, necessitating a more collaborative approach.

Purpose of the Study:

• To review shared and disease-specific clinical changes in childhood dementias.
• To explore these clinical changes as potential indicators of underlying pathophysiologic processes.
• To advocate for a collective approach to advance research, biomarker discovery, and therapeutic development.

Main Methods:

• Literature review of childhood dementias.
• Analysis of clinical phenotypes beyond cognitive decline.
• Discussion of implications for therapeutic development and care optimization.

Main Results:

• Childhood dementias present heterogeneous phenotypes including cognitive, eating, motor, pain, sleep, and behavioral changes.
• These physiological phenotypes are linked to neural network dysfunction and significant carer burden.
• Clinical manifestations can serve as indicators of pathophysiologic processes and potential therapeutic targets.

Conclusions:

• A collective approach to childhood dementia research is crucial for identifying biomarkers and streamlining therapeutic development.
• Understanding shared clinical phenotypes can guide the optimization of best practice management for affected children.
• This collaborative strategy promises to accelerate progress in treating rare pediatric neurodegenerative conditions.
