Visual hallucinations in older adults are common and often misunderstood. Seeing shapes, faces, or scenes that aren’t really there can be unsettling, but these experiences are not always a sign of dementia. Visual impairments, neurological conditions, medications, or social isolation — the causes are varied. This guide helps you recognize the signs, understand the possible causes, and adopt the right approach to best support your elderly loved ones.
Visual Hallucinations in the Elderly: What to Do?
Seeing shapes, people, or scenes that aren't actually there can be a disturbing experience — both for the elderly person experiencing it and for their loved ones. These visual hallucinations are not uncommon in seniors, and it is essential to understand that they are not always a sign of dementia or madness. Recognizing the causes and adopting the right responses can significantly improve quality of life.
What Is an Hallucination?
An hallucination is a sensory perception without any real external stimulus. In other words, the person sees, hears, smells, touches, or tastes something that isn’t present in their environment.
In the case of visual hallucinations, the person sees something no one else can: a figure, faces, lights, objects, or sometimes entire scenes.
These hallucinations can be transient, recurring, or chronic. They may be frightening, neutral, or in some cases, even comforting.
🧠 What Are the Possible Causes of Visual Hallucinations in the Elderly?
There are many potential causes, ranging from mild issues to more serious conditions. Here are the main ones:
1. 👁️ Vision Problems
- Charles Bonnet Syndrome: In elderly people with visual impairments (macular degeneration, cataracts, glaucoma…), the brain "compensates" for the lack of visual input by creating images. These hallucinations are not psychiatric in nature, and the person remains fully aware that what they see isn’t real.
- Eye strain or poorly corrected vision can also lead to false visual perceptions.
2. 🧓 Neurological Disorders
- Parkinson's disease or Lewy body dementia: hallucinations may occur at various stages, sometimes early on..
- Dementia or Alzheimer’s disease: in some cases, visual hallucinations are linked to changes in perception and memory.
- Stroke: damage to the visual areas of the brain can trigger hallucinations.
3. 💊 Medications or Drug Interactions
Some treatments — especially when combined (antidepressants, corticosteroids, anti-Parkinson’s medications, sleeping pills, etc.) — can produce hallucination-like side effects..
4. 🧬 Metabolic or Infectious Conditions
- Urinary tract infections (common in the elderly) can cause confusion and temporary hallucinations.
- Liver or kidney issues, low blood sugar, or severe dehydration can also alter awareness and perception.
5. 😟 Isolation, Anxiety, or Depression
Prolonged loneliness, stress, or psychological distress can create fertile ground for hallucinations, especially if the person has lost loved ones or is going through unresolved grief
✅ What to Do When an Elderly Person Experiences a Visual Hallucination?
It is essential to respond with empathy, calm, and care. Here are the steps and possible solutions to consider :
1. Don’t Deny What the Person Sees
Even if the hallucination isn’t real for you, it is real to them. Avoid saying: “You’re making that up” or “That’s not true.” Stay reassuring and open :
➡️ « I understand you're seeing something. Would you like to talk about it? »
2. Observe and Take Notes
- Time of day
- Context (fatigue, stress, lighting, isolation…)
- Frequency and duration
- Medications being taken
Keeping a symptom diary can help the doctor make an accurate diagnosis.
3. Consult a Healthcare Professional
- Start with a general practitioner, who can evaluate the most likely causes.
- If needed, consult an ophthalmologist, neurologist, geriatric psychiatrist, or geriatrician.
4. Review Medical Treatments
Ask a doctor or pharmacist to review medications for possible interactions or side effects.
5. Improve Living Conditions
- Optimize lighting in the home (soft but sufficient lighting)
- Stimulate the senses (soft music, walks, social contact)
- Maintain a healthy lifestyle (hydration, sleep, nutrition)
- Encourage social interaction to reduce isolation
6. Non-Medication Approaches
- Supportive psychotherapy, especially for individuals who are aware of their hallucinations
- Gentle yoga, meditation, or relaxation to calm the mind
- Occupational therapy to maintain cognitive function and focus
