Hearing Screening for Older Adults With Cognitive Impairment: A Systematic Review
- Increased Risk of Dementia: Studies indicate that individuals with hearing loss, even in midlife, have a higher risk of developing dementia later in life.
- Brain Health: Hearing loss may lead to changes in brain structure, particularly in areas involved in hearing, language, and memory.
- Social Isolation: Hearing loss can contribute to social isolation, which is another risk factor for cognitive decline.
- Preventive Measures: Treating hearing loss with hearing aids or cochlear implants may help slow cognitive decline.
Hearing loss is one of the top risk factors for dementia, according to a 2020 Lancet commission report. The rate of cognitive decline is thought to increase with increasing severity of hearing loss. People with mild hearing loss have almost double the risk of dementia than someone with normal hearing, and people with severe hearing loss have almost five times the risk. When hearing loss occurs, the brain may reallocate resources to help you hear, which can take a toll on your overall cognitive health. A 2011 study found that older adults with hearing loss were more likely to develop dementia than older adults with normal hearing. Senior adults with severe hearing loss were more likely to develop dementia when left untreated, according to a recent study by a research team at the Johns Hopkins Bloomberg School of Public Health.
It’s important to get your hearing checked regularly, especially if you notice difficulty following conversations or frequently asking others to repeat themselves. Early intervention can make a significant difference.

Cognitive decline can manifest in various ways, and it’s important to recognize the signs early. Here are some common indicators:
- Memory Loss: Frequently forgetting recent events, appointments, or conversations.
- Language Problems: Difficulty finding the right words or following conversations.
- Poor Judgment: Making poor decisions or having trouble with planning and problem-solving.
- Disorientation: Getting lost in familiar places or not recognizing familiar faces.
- Difficulty with Complex Tasks: Struggling to follow instructions, manage finances, or complete multi-step tasks.
- Changes in Mood or Behavior: Experiencing increased anxiety, depression, irritability, or apathy.
If you or someone you know is experiencing these symptoms, it’s a good idea to consult a healthcare professional for a thorough evaluation.

Cognitive decline can be caused by a variety of factors, including:
- Aging: Natural aging processes can lead to changes in brain structure and function, contributing to cognitive decline.
- Neurodegenerative Diseases: Conditions like Alzheimer's disease and Parkinson's disease are major contributors to cognitive decline due to the progressive loss of brain cells.
- Vascular Issues: Reduced blood flow to the brain, often due to conditions like hypertension or small strokes, can impair cognitive function.
- Chronic Health Conditions: Diabetes, heart disease, and other chronic illnesses can negatively impact brain health.
- Lifestyle Factors: Poor diet, lack of physical activity, smoking, and excessive alcohol consumption can all contribute to cognitive decline.
- Mental Health: Depression, anxiety, and chronic stress can also affect cognitive abilities.
Maintaining a healthy lifestyle, managing chronic conditions, and staying mentally and socially active can help mitigate some of these risks.
