# Anosognosia Explained: When Someone Cannot Recognise Their Own Rethink Mental Illness https://www.trowbridgeusersgroup.co.uk/2026/10/27/anosognosia-explained-when-someone-cannot-recognise-their-own-illness/

Have you ever wondered why someone experiencing a mental health crisis does not believe anything is wrong? Why might a person reject a diagnosis, refuse support or insist that their behaviour is perfectly normal when people around them are deeply concerned?
One possible explanation is **anosognosia**.
Understanding this condition can help us move away from judgement and towards a more compassionate understanding of mental health.
# # # What does anosognosia mean?
Anosognosia is a neurological condition in which a person has difficulty recognising or understanding their own illness, symptoms or impairments.
The word comes from Greek roots meaning, roughly, “not knowing a disease”.
In mental health, it is commonly associated with a reduced awareness of having a psychiatric condition or of the effects that condition may be having on everyday life.
For example, someone experiencing psychosis might genuinely believe that they are not unwell, even when their experiences and behaviour have changed significantly.
A person living with bipolar disorder might not recognise that they are experiencing mania. Someone with dementia might be unaware of the extent of their memory difficulties.
This is not necessarily a conscious decision to ignore a problem. The person's ability to recognise and evaluate their own condition may itself be affected.
# # # Is it the same as being in denial?
No. Although the two can look similar, they are not the same thing.
Psychological denial can involve avoiding or rejecting information because it is frightening, upsetting or difficult to accept.
Anosognosia involves a difficulty recognising the illness or impairment in the first place. The person may sincerely believe that nothing is wrong.
There can also be other reasons someone rejects a diagnosis, including previous negative experiences with healthcare, cultural differences, fear of stigma, disagreement with a professional or concerns about treatment.
We should never automatically label someone as experiencing anosognosia simply because they disagree with a diagnosis.
# # # Why can this happen?
Our brains help us interpret our experiences, understand our behaviour and compare our perception of ourselves with information from the world around us.
Certain neurological and psychiatric conditions can disrupt these processes. A person may struggle to recognise changes in their thinking, memory, behaviour or emotional state.
This can make it difficult to understand why other people are worried.
Anosognosia is not simply a lack of intelligence, and it does not mean that someone cannot understand anything about their situation. Awareness can vary between different symptoms and change over time.
# # # What might it feel like?
Imagine waking up one morning and finding that everyone around you is behaving strangely.
Your family is worried. Your friends are asking whether you are okay. A healthcare professional suggests that you need help.
But from your perspective, you feel that you are thinking clearly and that everyone else has misunderstood the situation.
You may feel frustrated, confused, threatened or unfairly judged.
This example illustrates why repeatedly telling someone that they are ill may not help. If they cannot recognise the problem in the way others do, an argument may only increase their distress.
# # # Why does understanding matter?
Anosognosia can affect whether someone seeks help, accepts treatment or recognises situations in which they need support.
It can also create considerable emotional strain for family members, friends and healthcare professionals.
Understanding the condition does not mean ignoring risks or assuming that every decision is appropriate. It means approaching difficulties with patience, accurate information and an individualised support plan.
**The key message:** Someone who does not recognise their illness is not automatically being stubborn, difficult or deliberately uncooperative. Their awareness may be affected by the very condition that others are trying to help them manage.
At Trowbridge Service Users Group, we believe that understanding must come before judgement. Everyone deserves to be treated with dignity, listened to and offered appropriate support.
