Disconnections: Hearing Loss, Isolation and Wellbeing

Hearing loss affects more than your ears. It makes conversation harder work, and over time many people start skipping the dinners, meetings and phone calls that keep them close to others. Research links untreated hearing loss with loneliness, social isolation and depression, and the 2024 Lancet Commission on dementia names hearing impairment as one of the two biggest modifiable risk factors for dementia, accounting for 7% of cases worldwide. The encouraging part is that hearing loss can be treated, and treatment, from hearing aids to simple changes in how families talk, can help people stay connected.

Key facts

• The World Health Organization estimates that 430 million people, over 5% of the world's population, need rehabilitation for disabling hearing loss, and lists "social isolation, loneliness and stigma" among its effects.
• A meta-analysis of 35 studies and 147,148 people found that older adults with hearing loss had 47% higher odds of depression (odds ratio 1.47) (Lawrence et al., The Gerontologist, 2020).
• The 2024 Lancet Commission estimates that 14 modifiable risk factors account for 45.3% of dementia, with hearing impairment and high LDL cholesterol the largest at 7% each (Livingston et al., 2024, accepted manuscript; Lancet press release).
• In the US, fewer than 1 in 3 adults aged 70 and older who could benefit from hearing aids have ever used them (NIDCD).
• In a randomized trial of 977 older adults, a hearing intervention with hearing aids reduced loneliness and social isolation over three years compared with health education (Reed et al., JAMA Internal Medicine, 2025).

How does hearing loss affect relationships?

Most of the strain shows up in everyday talk. Someone with hearing loss may ask people to repeat themselves, miss the punchline, answer the wrong question or nod along without following. Family members can read this as inattention or stubbornness, and the person with hearing loss can feel embarrassed or shut out. The US National Institute on Deafness and Other Communication Disorders (NIDCD) puts it plainly: hearing loss "can make it hard to enjoy talking with family and friends, leading to feelings of isolation." Its self-check questions include whether a hearing problem makes you feel frustrated when talking to family, or left out in a group.

Groups and noisy places are the hardest. A one-to-one chat in a quiet kitchen can go fine while a restaurant, a family gathering or a work meeting becomes exhausting, because the brain has to fill in the words it cannot hear. People often respond by talking less, leaving early or not going at all. That is how a hearing problem slowly turns into a social one.

Partners carry part of the load too. They may become the household interpreter, repeating what others said, making phone calls and turning the TV up or down. Raising hearing as a shared problem, rather than one person's failing, makes it easier to agree on solutions.

Is hearing loss linked to loneliness and social isolation?

Yes, and the link is consistent across studies, although most of the evidence is observational. A systematic review by Shukla and colleagues screened 2,495 studies and included 14 that used validated measures. Most multivariable-adjusted studies "found that hearing loss was associated with higher risk of loneliness and social isolation," and several found the link was stronger among women than men.

The two terms mean different things. Social isolation is about how much contact you have with other people; loneliness is the feeling that your contact is not enough. The 2024 Lancet Commission makes the same distinction, describing loneliness as "about people's feelings that their social contact is inadequate" (Livingston et al., 2024).

Loneliness is a large public health problem in its own right. A 2025 WHO Commission on Social Connection report found that 1 in 6 people worldwide is affected by loneliness, and linked it to more than 871,000 deaths a year. WHO lists poor health and living alone among its causes; hearing loss is one of the health problems that can push people toward it.

Does hearing loss raise the risk of depression?

The best pooled evidence says it is associated with higher risk. The 2020 meta-analysis by Lawrence and colleagues at Ear Science Institute Australia combined 35 studies with 147,148 participants. Hearing loss was linked to greater odds of depression in older adults, with an odds ratio of 1.47 overall, 1.54 in cross-sectional studies and 1.39 in cohort studies that followed people over time. The authors rated certainty in the overall estimate as "low," and they did not find that hearing aid use changed the association, though they advised caution on that point.

In practice, low mood and hearing loss can feed each other. Withdrawing from conversation reduces the contact and enjoyment that protect mental health, and low mood makes it harder to seek help. If you or someone close to you has both, it is worth raising both with a doctor at the same visit.

What did the Lancet Commission say about hearing loss and dementia?

The Lancet Commission on dementia prevention, intervention and care is a group of international experts who review the evidence on what raises dementia risk. Its 2020 and 2024 reports both put hearing loss near the top of the list of risks that can be changed.

The 2020 report said 12 modifiable risk factors "account for around 40% of worldwide dementias," with midlife hearing loss carrying the largest share at 8.2% and a relative risk of 1.9 (full text via Europe PMC). It also stated that "using hearing aids appears to reduce the excess risk from hearing loss."

The 2024 report added high LDL cholesterol and untreated vision loss, bringing the total to 14 factors. The authors estimated the combined population attributable fraction at 45.3% (accepted manuscript). According to the Lancet press release, hearing impairment and high LDL cholesterol were the largest contributors at 7% each, followed by less education in early life and social isolation in later life at 5% each.

Measure	2020 Lancet Commission	2024 Lancet Commission
Number of modifiable risk factors	12	14
Share of dementia linked to all factors	About 40% (39.7%)	45.3%
Share linked to hearing loss	8.2% (midlife)	7%
Share linked to social isolation	3.5% (later life)	5% (later life)
Hearing loss risk estimate	Relative risk 1.9	Hazard ratio 1.37 in a new meta-analysis of 666,370 people

Two cautions matter. First, these shares assume each factor causes dementia, which the Commission states as an assumption, not a proven fact. Second, 7% is a population figure, not a personal one. It does not mean that a person with hearing loss has a 7% chance of dementia. The 2024 report also found that risk rises with severity: every 10 dB decrease in hearing ability was linked to higher dementia risk in all four studies that tested a dose response.

Why might hearing loss matter for the brain? The Commission discusses several possible routes, including reduced social contact, the extra effort of decoding degraded sound and changes in brain structure. Its 2024 report notes that "psychosocial factors such as loneliness, depression and social isolation may be involved," which connects the dementia question back to relationships.

Do hearing aids help with isolation, mood and memory?

The evidence is strongest for communication and quality of life, mixed for loneliness, and still developing for cognition.

Study	What it tested	Main finding
Cochrane review, 2026	16 randomized trials, 2,261 adults with mild to moderate hearing loss	Large benefit for hearing-specific quality of life and listening ability; little to no difference in loneliness (2 studies, low certainty)
ACHIEVE trial, Lancet, 2023	Hearing intervention vs health education, 977 adults aged 70 to 84	No difference in 3-year cognitive decline overall; a benefit signal in the higher-risk ARIC group
ACHIEVE secondary analysis, 2025	Social isolation and loneliness in the same trial	Hearing intervention reduced social isolation and loneliness over 3 years
Meta-analysis cited in the 2024 Lancet report	8 cohort studies, 126,903 people	Hearing aid users had 19% lower risk of cognitive decline and 17% lower risk of dementia
JAMA Otolaryngology review, 2025	65 studies of hearing aids and cochlear implants	Better social quality of life and less perceived social handicap; loneliness results inconclusive

The ACHIEVE secondary analysis is the most direct test of the social question. Over three years, average social network size fell from 22.6 to 21.3 people in the hearing group and from 22.3 to 19.8 people in the control group (Reed et al., 2025). The hearing group also kept a more diverse network and reported less loneliness. The Cochrane review, which pooled shorter trials, did not find a clear loneliness effect, so the honest summary is that hearing aids reliably help people hear and take part, and may help with loneliness over longer periods.

What helps people stay connected?

Treating the hearing loss is the starting point, but habits around it matter just as much.

Get a hearing test. Many people wait years before acting. In the US, fewer than 1 in 3 adults aged 70 and older who could benefit from hearing aids have ever used them, and about 16% of adults aged 20 to 69 who could benefit have done so (NIDCD).

Know what support exists where you live.

• Australia: eligible pensioners can get fully subsidised hearing aids, including assessment and fitting, through the Australian Government Hearing Services Program (Hearing Australia; eligibility at health.gov.au).
• UK: hearing aids are available on the NHS, "provided for free as a long-term loan," usually after a GP referral (NHS).
• US: since October 17, 2022, adults 18 and older with perceived mild to moderate hearing loss can buy over-the-counter hearing aids without a prescription (FDA).

Change how conversations happen. The NIDCD suggests facing the person so they can see your face and lips, turning down the TV or other background noise first, speaking up without shouting, and slowing down. When eating out, pick a booth or a quiet corner away from the kitchen or live music.

Keep showing up. Social contact is a risk factor in its own right in the Lancet reports. Choosing smaller groups, quieter venues and daytime meetups can make it easier to stay involved while hearing is being treated.

Protect the hearing you have. WHO estimates that over 1 billion young adults are at risk of permanent, avoidable hearing loss from unsafe listening (WHO). Lower volumes, shorter sessions and earplugs at loud events reduce the chance of joining that group, and the 2024 Lancet Commission recommends reducing harmful noise exposure alongside making hearing aids available to all who need them (press release).

Frequently asked questions

Can hearing loss cause dementia?

It is a strong risk factor, but cause is not proven. The 2024 Lancet Commission estimates that 7% of dementia worldwide is linked to hearing impairment, assuming the relationship is causal, and the ACHIEVE trial found no overall cognitive benefit from hearing aids over three years, with a possible benefit in higher-risk adults.

Will hearing aids stop me feeling lonely?

They can help, though results vary. A three-year trial found that a hearing intervention reduced loneliness and social isolation in older adults (Reed et al., 2025), while a 2026 Cochrane review of shorter trials found little to no difference in loneliness.

Is depression more common in people with hearing loss?

Yes. A meta-analysis of 35 studies found older adults with hearing loss had 1.47 times the odds of depression (Lawrence et al., 2020). The evidence is observational, so it shows a link rather than proof that one causes the other.

How can I help a family member with hearing loss?

Face them when you speak, cut background noise, speak clearly without shouting and choose quieter places to meet (NIDCD). Encourage a hearing test and offer to go along.

What was the Disconnections page on hearsmart.org about?

The address hearsmart.org was previously used by HEARsmart, a separate Australian hearing loss prevention project that has no connection with this site. This page covers the same broad subject, the social and emotional effects of hearing loss, with current sources.
