Anosognosia is a condition that affects individuals with mental health conditions, structural brain lesions, and dementia. It is characterized by a lack of awareness of one’s disease or disorder and poor insight into their symptoms and their impact on everyday functioning. In this article, we will understand anosognosia, its causes, symptoms, and treatment.
What is Anosognosia?
The word anosognosia comes from Greek roots and roughly means “to not know a disease.” It refers to the lack of awareness that an individual has about their illness and the need for treatment. People with anosognosia may doubt their diagnosis, attribute their symptoms to other causes, or sincerely believe that they do not need help. They may also become defensive when someone brings up their health.
Causes of Anosognosia
A person’s ability to observe and organize new information about themselves plays a significant role in awareness and insight. If the frontal lobe does not recognize the symptoms of an illness, the person may be left with a pre-illness self-image and a lack of insight into their current health status.
In some cases, brain injury or damage can also cause anosognosia. This can happen when brain lesions cause damage to one side of the brain or after experiencing a stroke where the person loses awareness on the recovering side of their body.
Anosognosia can also be associated with several health conditions such as mood disorders like major depressive disorder (MDD) and bipolar disorder, psychotic disorders like schizophrenia, cognitive and neurological conditions like Alzheimer’s disease and dementia (memory impairment), Huntington’s disease, Parkinson’s disease, as well as psychosocial factors like personality, beliefs, and values.
Symptoms of Anosognosia
The symptoms of anosognosia can manifest in various ways. Some individuals may have partial awareness of their illness and symptoms, while others may have no awareness at all. Common symptoms include a lack of awareness of one’s disability or deficit, denial of health conditions or problems, inaccurate perception of mental health, not recognizing the need for treatment, and not following through with treatment. It can also lead to difficulties with social tasks.
It is essential to note that anosognosia differs from denial in several ways. For instance:
- The lack of insight in anosognosia can last for years, while denial may be temporary.
- Beliefs in anosognosia remain even when presented with strong evidence to the contrary.
- Individuals with anosognosia may use illogical explanations to justify their experience.
Prevalence
The prevalence of anosognosia varies depending on the underlying cause. According to early studies from the 1990s, approximately 30% of people with schizophrenia and 20% of people with bipolar disorder experience a severe lack of awareness about their illness.
If you or someone you know is experiencing symptoms of anosognosia, it is essential to seek professional help for proper diagnosis and treatment.
