Holly Schiff, Psy.D.While dementia is a neurological condition known for its impact on memory, thinking, and behavior, anosognosia involves a lack of awareness about one’s health condition. When these conditions occur together, they can make it difficult for someone to recognize their cognitive decline and accept the support they need.
A closer look at both dementia and anosognosia and how they overlap offers valuable insights for caregivers and those living with the conditions.

Key takeaways
- Anosognosia can prevent a person with dementia from recognizing cognitive difficulties or the need for help.
- This neurologically based loss of awareness differs from psychological denial and can complicate treatment and safety.
- Individualized care and support for caregivers can help manage resistance, daily needs, and emotional strain.
What is Dementia?
Affecting roughly 57 million people worldwide, dementia comprises a group of neurological conditions that impair cognitive abilities, including memory, reasoning, communication, coordination, mood, and behavior [1]. As such, dementia isn’t a single disease but rather an umbrella term encompassing various disorders that affect brain function.
More common in those 65 and older, dementia is characterized by cognitive issues that worsen over time. Early signs and symptoms of dementia include [1]:
- \n
- Losing track of time \n
- Experiencing problem-solving and decision-making difficulties \n
- Forgetting recent events \n
- Losing items \n
- Being unable to perform familiar tasks effectively \n
- Getting lost \n
- Being confused in familiar places \n
- Experiencing difficulty following and participating in conversations \n
People with dementia also experience mood and behavior changes. They may exhibit inappropriate behavior, withdraw from everyday activities, or show decreased interest in others and their emotions [1].
Types of Dementia
The various types of dementia are sometimes categorized into three main groups: primary, secondary, and reversible. Primary dementia occurs when dementia is the main illness. These include [2]:
- \n
- Alzheimer’s disease \n
- Frontotemporal dementia \n
- Lewy body dementia \n
- Mixed dementia \n
- Vascular dementia \n
Meanwhile, secondary dementia and reversible dementia are caused by other diseases or conditions. The difference is that reversible dementia is due to conditions like infections and vitamin deficiencies, and resolves fairly quickly with proper treatment [2].
As with many other medical conditions, dementia often occurs alongside other conditions such as diabetes and even epileptic seizures [3][4]. Beyond physical health issues, cognitive symptoms like anosognosia are frequently linked to dementia [5].
What is Anosognosia?
Anosognosia (uh-no-sog-NOH-zee-uh) is a neurological condition where a person is unaware of their illness or the challenges it creates in their daily life. This lack of awareness isn’t denial or stubbornness. Rather, it stems from changes in the brain that impair self-perception and insight. Those experiencing anosognosia often believe nothing is wrong with them or minimize their symptoms even when cognitive decline is obvious to others [5].
The main causes of anosognosia include [5]:
- \n
- Brain damage: Strokes or brain injuries can impact areas of the brain responsible for self-awareness. \n
- Degenerative diseases: Brain diseases that disrupt neural connections, like Alzheimer's and Huntington's diseases, are linked to anosognosia. \n
- Psychiatric conditions: A link also exists between anosognosia and mental illness, as some conditions like schizophrenia and severe bipolar disorder are associated with anosognosia. \n
How Are Dementia and Anosognosia Linked?
Anosognosia is a common symptom associated with dementia. In fact, it impacts more than 80% of people with Alzheimer’s disease and 94.5% of all cases of early-onset dementia [5][6]. It manifests as an inability to recognize one’s own cognitive impairments. For example, someone who struggles with dementia-related memory loss may insist that their memory is fine.
The presence of anosognosia in dementia complicates caregiving and treatment. A person may resist medical advice, decline therapy, or refuse assistance, believing they are still capable of independence. Understanding the link between dementia and anosognosia is essential for creating effective care plans and ensuring better outcomes.
Anosognosia vs. Denial
Anosognosia and denial may appear similar on the surface, but a closer look shows they are fundamentally different. Denial is a psychological defense mechanism where someone consciously or subconsciously refuses to accept a diagnosis or health condition, often as a way to avoid emotional distress. For example, they might avoid discussing their symptoms or refuse treatment because acknowledging the condition feels too overwhelming or distressing.
In contrast, anosognosia is caused by physical changes or damage in the brain, which impair self-awareness and make it impossible for a person to recognize their condition [5]. With anosognosia, the person is genuinely unaware of their impairments, rather than consciously or subconsciously refusing to address them.
Distinguishing between these two concepts is important when working with someone who seems unaware of their health challenges. If the person has anosognosia, attempts to reason with or convince them may be ineffective. Conversely, in cases of denial, talk therapy and empathy may help the person gradually come to terms with their diagnosis.
Treatment for Anosognosia and Dementia
While no cure exists for most forms of dementia, certain treatments and strategies can help manage symptoms, improve quality of life, and address the challenges caused by anosognosia and related conditions. Treatment options for dementia include [7]:
- \n
- Medications: Donepezil (Aricept), a type of enzyme inhibitor, can elevate the chemical messengers involved in judgment and memory. Meanwhile, memantine (Namenda) regulates glutamate, which is involved in learning and memory. Additionally, medications such as lecanemab (Leqembi) can slow declines in thinking and functioning. \n
- Occupational therapy: This therapy teaches adaptive skills and coping strategies and helps ensure home safety. For instance, reducing environmental clutter and noise can also aid functioning and focus. \n
- Lifestyle changes: Establishing routines, adjusting the speed and difficulty level of conversations, and encouraging engagement in exercise and activity can promote safety and aid in symptom management. \n
- Other therapies: Various therapies, including music, pet, massage, and art therapy, can help reduce agitation and promote relaxation. \n
When people have both dementia and anosognosia, caregivers often focus on strategies to improve safety and ensure adherence to treatment plans. Ultimately, treatment for both conditions requires a personalized approach that considers the person’s specific symptoms, safety needs, and overall health.
Impact of Anosognosia on Caregiving
Caring for someone with dementia and anosognosia can be exceptionally challenging. The lack of awareness can create significant stress for caregivers, as they must navigate both the practical and emotional complexities of providing support to someone who may not understand why that care is necessary.
One of the most challenging aspects is ensuring safety. Someone with anosognosia may insist they are capable of tasks they can no longer perform, such as driving, cooking, or managing medications. Caregivers often have to step in to manage these risks, which can be emotionally taxing.
Along with frustration, caregivers often experience feelings of guilt, burnout, and isolation. In fact, research shows that caregivers for those with both dementia and anosognosia are at greater risk of stress-related health issues compared to those caring for people who retain awareness of their condition [8].
Despite these difficulties, several strategies can help. Building trust through calm, non-confrontational communication and focusing on creating a safe and structured environment can make caregiving more manageable.
Additionally, support groups and resources designed for those living with dementia and their caretakers can provide emotional relief and practical advice. By seeking assistance and prioritizing their own well-being, caregivers can better navigate the challenges of anosognosia and dementia care while maintaining their health and resilience [9].
Navigating Dementia and Anosognosia
Dementia, with its progressive impact on memory, thinking, and behavior, often intersects with anosognosia, a neurological condition that impairs self-awareness. Together, they can complicate diagnosis, treatment, and daily life, requiring thoughtful and compassionate approaches to care.
While there are no cures for most forms of dementia, treatments and strategies can help manage symptoms, improve quality of life, and address the effects of the disorder. For caregivers, understanding the nature of these challenges and seeking support can make a meaningful difference while navigating care.
Despite the difficulties, hope remains. Advancements in research and supportive interventions continue to improve outcomes for those living with dementia and their loved ones. By promoting compassion, communication, and awareness, it’s possible to create a better future for everyone impacted by these conditions.
