What Is Deafblindness?

Deafblindness is a condition that involves a combination of vision and hearing loss that significantly limits communication, mobility, and access to information. It is not always a complete loss of both senses. Some individuals may be completely blind and deaf, while others retain partial hearing or vision, which may fluctuate or worsen over time. This dual sensory impairment presents unique challenges but also creates opportunities for highly personalized ways of interacting with the world.

Despite the barriers it can create, deafblindness does not mean a person cannot live a full, active, and independent life. With the right support systems, communication tools, and adaptive technologies, many people who are deafblind pursue careers, build relationships, and participate fully in their communities.

Causes of Deafblindness

The causes of deafblindness can vary greatly depending on whether the condition is present from birth or acquired later in life. Understanding the root cause often helps guide appropriate treatment, communication strategies, and support.

Congenital deafblindness, meaning present at birth or occurring shortly after, is often the result of:

• Genetic conditions, such as Usher syndrome or CHARGE syndrome

• Infections during pregnancy, like rubella, cytomegalovirus (CMV), or toxoplasmosis

• Premature birth or complications during delivery that affect brain or sensory organ development

In contrast, acquired deafblindness typically develops later due to:

• Age-related hearing and vision loss, which is especially common in older adults

• Diseases, such as diabetes, stroke, or meningitis

• Injury or trauma, including head injuries or accidents

• Progressive genetic conditions, where symptoms emerge or worsen over time

For instance, Usher syndrome is one of the most common genetic causes of combined hearing and vision loss. It typically presents as congenital hearing loss followed by progressive vision loss caused by a retinal disorder known as retinitis pigmentosa. People with Usher syndrome may start to notice vision problems in adolescence or early adulthood, creating new communication challenges as their visual field narrows.

How Deafblindness Affects Communication and Daily Life

Living with deafblindness requires adapting to a world that often relies heavily on sound and sight. Because these two senses are key to how most people communicate and gather information, losing access to both can make even everyday tasks difficult without the right support.

Communication is often the most immediate and pressing challenge. Depending on the degree and onset of the sensory loss, individuals may rely on various methods to express themselves and understand others. These include:

• Tactile sign language, where signs are felt through touch rather than seen

• Braille, a system of raised dots used for reading and writing by touch

• Print-on-palm technique, in which words are spelled out on the hand

• Speechreading (lipreading), if some residual vision remains

• Assistive technology, such as speech-to-text software or vibrating alerts

Mobility can also be impacted. People with deafblindness may need orientation and mobility training, such as learning how to use a cane, navigate with a guide dog, or interpret tactile markers in public spaces. Many also benefit from the support of interveners or interpreters who help relay information about their surroundings in accessible ways.

Social connection, education, and employment are all achievable but may require accommodations and advocacy. With proper tools and a supportive network, individuals who are deafblind can continue to engage meaningfully with the world around them.

Hearing Aids and Assistive Technology for Deafblind Individuals

Technology plays a crucial role in helping people with deafblindness maintain independence and engage with their environment. For individuals who still have some degree of hearing, hearing aids can be incredibly helpful in amplifying sound and enhancing situational awareness.

The right technology solution depends on the person’s specific needs and sensory profile. In many cases, hearing devices are used in tandem with tactile or visual supports. Some of the most effective tools include:

• Digital hearing aids, such as the Audicus Omni 2, which offer Bluetooth streaming, directional microphones, and noise filtering to support remaining auditory perception

• Cochlear implants, which bypass damaged parts of the ear and send signals directly to the auditory nerve

• Braille displays, which convert text on a screen into Braille for reading

• Vibrating alert systems, including alarm clocks, doorbells, and emergency alerts

• Screen readers and speech-to-text apps, which provide audio or text-based versions of content for easier access

Even simple technologies, such as a vibrating watch or a flashlight signal system, can enhance safety and communication at home and in public. Importantly, many of these tools can be personalized and layered to match the individual's specific hearing and vision capabilities.

Support Services and Advocacy Resources

A network of organizations exists to support individuals living with deafblindness and their families. These services can include everything from early diagnosis and intervention to lifelong support with communication, employment, and independent living.

Trusted resources include:

• Helen Keller National Center for DeafBlind Youths and Adults, which provides vocational and independent living training

• State-level Departments of Vocational Rehabilitation (DVR), which may offer hearing aids, communication devices, and employment support

• National Institutes on Deafness and Other Communication Disorders (NIDCD), which funds research and offers public education

• National Federation of the Blind (NFB) and American Association of the DeafBlind (AADB), both of which advocate for accessibility, civil rights, and community inclusion

These organizations often work in partnership with schools, employers, and medical professionals to ensure individuals with deafblindness have the tools and accommodations they need. Families and caregivers can also find valuable training, respite resources, and emotional support through these networks.

Living with Deafblindness: Real-Life Stories and Examples

Despite the challenges associated with dual sensory loss, many people who are deafblind live full, vibrant lives. Stories from real individuals and communities highlight the creativity and resilience behind each journey.

One powerful example is the Nalaga’at Theater Group in Israel, where a cast of deafblind actors performs through movement, scent, and vibration. Their internationally acclaimed play Not by Bread Alone gives audiences insight into their inner world, showing how the human experience can be shared without traditional sound or sight.

In the United States, individuals with conditions like Myhre syndrome, Alström syndrome, or Usher syndrome are increasingly using hearing aids, tactile sign language, and mobile apps to communicate with friends, attend school, and enter the workforce. Some people rely on cochlear implants and Braille readers, while others use a combination of high- and low-tech tools.

These stories serve as a reminder that people with deafblindness are not defined by their condition but by their capacity to adapt, connect, and thrive.

How to Help or Advocate for Someone with Deafblindness

Whether you're a caregiver, educator, friend, or healthcare provider, supporting someone with deafblindness involves patience, empathy, and a willingness to learn. The right mindset and small everyday adjustments can make a significant difference.

Before offering help, it’s essential to understand how the individual prefers to communicate. Ask what tools or strategies they use. Some may be comfortable with tactile signing or print-on-palm communication, while others rely on speech or assistive devices.

Here are a few helpful strategies:

• Be clear and direct in your communication, and give the person time to respond without rushing them

• Avoid making assumptions, especially about what they can or cannot do

• Ensure environments are safe and accessible, which might involve using vibration-based alerts or minimizing background noise

• Support their autonomy, especially when navigating spaces, making decisions, or managing their technology

Being an advocate can also mean helping the person access funding for hearing aids, locate a vocational counselor, or find a local peer support group. Small efforts can empower individuals with deafblindness to lead more independent and connected lives.
