they may instead be experiencing “lack of insight” or “lack of awareness.” the formal medical term for this medical condition is anosognosia, from the greek meaning “to not know a disease.” when we talk about anosognosia in mental illness, we mean that someone is unaware of their own mental health condition or that they can’t perceive their condition accurately. anosognosia is a common symptom of certain mental illnesses, perhaps the most difficult to understand for those who have never experienced it. self-awareness can vary over time, allowing a person to acknowledge their illness at times and making such knowledge impossible at other times. when we get a sunburn, we adjust our self-image and expect to look different in the mirror. when we learn a new skill, we add it to our self-image and feel more competent. it requires the brain’s frontal lobe to organize new information, develop a revised narrative and remember the new self-image.
when the frontal lobe isn’t operating at 100%, a person may lose—or partially lose—the ability to update his or her self-image. if family and friends insist they’re right, the person with an illness may get frustrated or angry, or begin to avoid them. early studies of anosognosia indicated that approximately 30% of people with schizophrenia and 20% of people with bipolar disorder experienced “severe” lack of awareness of their diagnosis. learning to understand anosognosia and its risks can improve the odds of helping people with this difficult symptom. for a person with anosognosia, this inaccurate insight feels as real and convincing as other people’s ability to perceive themselves. lack of insight also typically causes a person to avoid treatment. and, as it is often combined with psychosis or mania, lack of insight can cause reckless or undesirable behavior.
although research in the field is limited at this time, there is hope that anosognosia as a symptom of schizophrenia will become a focus of further research and a critically important therapeutic target amenable to treatment. investigators with more focused interests in the phenomenology and effects of insight deficits have developed dedicated, multidimensional insight scales. there is currently no established treatment other than prevention to address primary negative symptoms, and pharmacologic treatments have a limited impact on symptoms.19 it is important to identify patients in the early stages of psychosis or who are at high risk for developing psychosis in order to reduce dup. the term anosognosia now more broadly refers to a neurologically based denial of illness and unawareness of disability, not limited to patients with hemiplegia.
shad et al29 also published a review of 34 english-language studies that investigated the relationship between frontal lobe function as measured by neurocognitive tests, and insight deficits in subjects with schizophrenia. eight subjects with schizophrenia and eight healthy control subjects underwent scanning during a task in which they attempted to control the motion of a virtual hand using a joystick. these findings tentatively support the hypothesis that poor insight may be related to impaired self-related processing.” in other words, poor insight was associated with a relative breakdown of dmn connectivity and operations. poor insight is a cardinal symptom of schizophrenia that, while not universally and uniformly expressed in all patients, is among the most common of its manifestations. effective approaches to this problem will allow patients, families, and care providers to engage in a collaborative paradigm rather than the antagonistic tug-of-war that characterizes relationships with illness-denying individuals and often tragically concludes with losses of those relationships altogether.

anosognosia, also called “lack of insight,” is a symptom of severe mental illness experienced by some that impairs a person’s ability to understand and perceive his or her illness. it is the single largest reason why people with schizophrenia or bipolar disorder refuse medications or do not seek treatment. anosognosia is a neurological condition that affects how people view themselves and impairs their awareness of their mental health symptoms. it furthermore, they argue that poor insight in patients with schizophrenia may be due to brain dysfunction. they point out numerous similarities anosognosia is a result of changes to the brain. it’s not just stubbornness or outright denial, which is a defense mechanism some people use, .
