Communication disorders: what to look for, and when to refer

Area of Science:

• Geriatrics
• Neurology
• Speech and Language Pathology

Background:

• Communication impairments, with or without swallowing disorders, are prevalent in the aging population.
• Conditions like aphasia, cognitive-communicative impairments, dysarthria, apraxia of speech, and dysphagia significantly impact quality of life.
• These disorders can lead to social isolation and depression, underscoring the need for timely intervention.

Purpose of the Study:

• To highlight the common communication disorders in older adults.
• To differentiate between various types of communication impairments and their underlying causes.
• To emphasize the role of primary care physicians in diagnosing and managing these conditions.

Main Methods:

• Review of common communication disorders in older adults.
• Discussion of diagnostic criteria for conditions such as aphasia, cognitive-communicative impairment, dysarthria, apraxia of speech, and dysphagia.
• Outline of the primary care physician's role in initial workup and referral.

Main Results:

• Aphasia, resulting from focal lesions, affects language but not cognition.
• Cognitive-communicative impairments are linked to deficits in memory, attention, or visual perception.
• Voice and speech disorders can cause social isolation; dysphagia may co-occur or be independent.

Conclusions:

• Primary care physicians can effectively diagnose communication disorders in older adults through in-office evaluations.
• Identifying patients with aphasia, cognitive-communicative impairments, or dysphagia is crucial for appropriate referral.
• Referral to specialists like otolaryngologists and speech-language pathologists ensures comprehensive patient care.
