Symptoms of Deafblindness
Symptoms of deafblindness depend on the severity and progression of both hearing and vision loss. While some people with deafblindness experience total blindness and deafness, others retain some usable sight or hearing. Because the condition affects two major senses, the symptoms create a range of functional challenges that impact communication, mobility, and independence.
Communication Difficulties
One of the earliest and most noticeable symptoms is difficulty communicating:
Individuals may struggle to follow conversations, especially in noisy environments or if visual cues like lip reading are limited
Spoken language may become less effective as hearing declines
Reading standard print or interpreting visual gestures can become increasingly difficult as vision worsens
These combined impairments severely restrict the ability to use conventional communication methods, requiring alternative approaches such as tactile sign language, braille, or assistive technology.
Orientation and Mobility Issues
People with deafblindness often have difficulty navigating their environment:
Poor depth perception or blurred vision combined with hearing impairment can lead to frequent falls, bumps, or injuries
Difficulty detecting oncoming traffic, environmental hazards, or spoken warnings increases risk during travel
Many experience disorientation in unfamiliar settings and may avoid public spaces altogether
Mobility aids such as canes, guide dogs, and orientation and mobility (O&M) training are essential for increasing safety and confidence.
Cognitive and Developmental Symptoms
For children with congenital deafblindness:
Developmental delays are common, particularly in speech, motor coordination, and social interaction
Without early intervention, cognitive development may be significantly impaired due to limited environmental input
Social and Emotional Challenges
Feelings of isolation, depression, and anxiety are frequent, particularly if support systems are weak
Reduced access to group activities, social gatherings, and everyday interactions can diminish self-esteem and increase emotional withdrawal
Progressive Symptoms | Symptoms of Deafblindness
In some cases, symptoms worsen over time, especially in progressive conditions like Usher syndrome. This requires ongoing adjustments to communication methods and support plans.
Symptoms in the Elderly
Older adults may not report their sensory difficulties, mistaking them as normal ageing. Symptoms may include:
Repeatedly asking people to repeat themselves
Difficulty recognising faces or navigating familiar spaces
Withdrawing from conversations or social events
In summary, symptoms of deafblindness manifest across multiple domains, affecting communication, independence, and emotional wellbeing. Early recognition allows for timely intervention and improved quality of life.
