Imagine suddenly seeing someone in your place, but when you look, there is no one. Or maybe it's an animal, or maybe it's just a light that appears and then disappears. This can be a really scary and shocking experience. Many people think this is a mental illusion, a mental phobia. But in medicine, we call this a visual hallucination .
Although this is scary, it means that something else is happening in your body or mind. So if this is happening to you, you should definitely talk to your doctor about it. That is the first and most important step to get rid of this condition.
Why is this happening? What are the reasons?
There can be many reasons for seeing things that aren't there. They range from mental health conditions to problems with your sleep. Let's look at some of the main reasons.
This condition can be caused by alcohol and illegal drug use . People who drink alcohol excessively and use drugs such as `(Ecstasy)`, `(Cocaine)`, `(LSD)` may see different lights, shapes, or even human figures. Also, such things are possible even if they have used these for a long time and then stopped suddenly.
In addition, various medical conditions can also cause visual hallucinations. Let's explain more about this in the table below.
| Condition/Cause | A simple explanation |
|---|---|
| Alzheimer's disease and other dementia conditions | In the later stages of the disease, changes in the brain can cause hallucinations. In particular, in the case of Lewy body dementia, a whole chain of events can seem to be happening before your eyes. |
| Brain tumors | If the tumor presses on the part of the brain responsible for vision, you may see very clear, lifelike visions. |
| Charles Bonnet syndrome | This is common in older people with vision impairments (e.g., macular degeneration, cataracts ). They themselves know that what they are seeing is an illusion. |
| High fever and infections | Hallucinations can occur during certain infections and high fevers, such as meningitis, especially in young children. |
| Intense stress | Not just normal everyday stress, but during times of unbearable stress or trauma (e.g., after the death of someone very close), you may feel as if you are seeing that person. |
| Mental illness | It is common in conditions such as schizophrenia . Although voices are often heard, sometimes family members, animals, or even religious figures can be seen. In addition, it can rarely occur in conditions such as (Bipolar disorder), (Borderline personality disorder), and (PTSD) . |
| Migraines | Some people with migraines experience an 'aura' before the headache. This can include seeing things like flashing lights and zig-zag patterns. |
| Parkinson's disease | About half of these patients experience hallucinations. These are usually not dangerous; they feel like they are watching someone from across the room doing something. |
| Side effects from medicine | This condition can occur due to the dosage of some medications, especially when elderly people take several medications at the same time. |
| Sleep issues | It's common to see something when falling asleep or waking up. These can feel like dreams. They're more common in people who have insomnia or narcolepsy . |
The important thing is that, regardless of the cause, ignoring this can be dangerous. Therefore, it is wise to seek medical advice immediately.
How do you find this, Doctor?
When you go to see a doctor, he or she will first examine you thoroughly and talk to you about your medical history and symptoms . You may often be asked questions like these:
- What exactly do you see? People, animals, shapes?
- When did this start?
- Does this happen at a specific time of day? (e.g., when going to bed)
- Do you have any other symptoms (e.g. headaches ) when you see these things?
- Are the things you see scary? Threatening? Or just normal?
Your answers to these questions will give your doctor a good idea of what tests to do next. For example:
- Psychiatric evaluation: To determine if there is a mental illness.
- Blood tests: To check for infections or other problems in the body.
- EEG (Electroencephalogram): A test to check for problems with the electrical activity of the brain, such as epilepsy.
- Eye Exam : To confirm whether there is any vision impairment.
- MRI scan: To check for a brain tumor, stroke, or other structural problem.
What are the treatments for this?
The treatment for this depends entirely on the underlying cause of your hallucinations. In most cases, once the underlying cause is treated, the hallucinations will stop.
Simply put,
- If it's a side effect of a medication you're taking, your doctor will change the dosage of that medication or prescribe a different medication.
- In the case of a brain tumor , treatment options include surgery, radiation, or chemotherapy. If it is a mental illness like schizophrenia , a treatment plan will be provided that combines medication, therapy, and other treatments.
That means, whatever the cause, there is a treatment that works for it. The most important thing is to see a doctor as soon as possible for an accurate diagnosis.
Take-Home Message
- Although seeing things that aren't there (visual hallucinations) can be scary, there is almost always a medical reason behind it.
- This can be due to various reasons, such as mental illness, brain diseases, certain medications, drugs, excessive fatigue, and sleep problems.
- If you or someone you know has experienced this, never ignore it. See a qualified doctor (doctor) as soon as possible.
- Once the cause is identified, treatment can completely control or cure the condition.
