What is Apathy?

In medical terms, apathy is defined as a lack of goal-directed activity and motivation compared to a person’s previous level of functioning. It also presents as a lack of spontaneity, interest, or emotional expression^[1]. The term comes from the Greek word “pathos,” which means passion or emotion, combined with the prefix “a-” meaning “not” or “lack.” Thus, apathy literally means a lack of those feelings^[3].

Apathy is not simply laziness or a choice of personal indifference. In the medical sense, it is something a person has no control over^[1]. Healthcare professionals consider it both a symptom and a syndrome (a collection of symptoms that often happen together)^[1]. An expert panel has defined specific criteria for diagnosing apathy, requiring that symptoms persist for at least four weeks and affect at least two of three dimensions: behavior/cognition, emotion, or social interaction^[4].

In everyday life, people often consider apathy to be the opposite of empathy—the ability to understand and share the feelings of others. However, in a medical context, apathy is not just a lack of feeling toward other people. It is a lack of motivation and interest in general^[1].

Signs and Symptoms

Apathy can manifest in various ways, and the symptoms may affect different aspects of a person’s life. Common signs include^[1][2]:

• Disengaging or withdrawing from work, hobbies, or spending time with loved ones. However, people with apathy often appear to enjoy spending time with loved ones if they are pushed or persuaded to do so
• A lack of concern about having disengaged from activities they used to enjoy. Family members and loved ones are more likely to notice the change in behavior and be concerned about it
• Relying on others to help fulfill daily activities, not because they are mentally or physically unable to do the tasks, but because they lack the self-directed motivation to do them
• A decrease in or lack of expression of both positive and negative emotions, called emotional blunting
• Not feeling strong emotions or emotionally reacting to situations as expected
• Fatigue and loss of energy for handling usual responsibilities or activities of daily life
• Difficulty concentrating
• Loss of interest in social activities or events
• A tendency to spend more time alone

People with apathy may speak in a monotone voice and use limited facial expressions or body language when communicating. They may also show a loss of enthusiasm, initiative, and a general “don’t care” attitude^[6].

Apathy vs. Depression

Apathy can resemble depression, but they are distinct conditions. People with apathy do not have the feelings of low mood or sadness that people with depression do^[1]. Depression brings about feelings of worthlessness, guilt, hopelessness, and despair that last for at least two weeks, whereas a person with apathy feels no mood or emotionally flat^[2][13].

While apathy is not an automatic sign of depression, it can be a symptom of it. Depression does not always involve apathy, and a person can experience apathy without having depression. However, a person can have both depression and apathy at the same time^[2][3].

Feeling “blah” about life is common in both conditions, but the key difference is emotional content. Rather than feeling sadness or anger, people with apathy simply do not feel much of anything. Things that used to make them happy no longer excite them^[3].

Types of Apathy

Researchers have identified different types and contexts of apathy:

Situational apathy is the result of a difficult circumstance or event, such as the loss of a loved one, changing schools or jobs, or suffering a financial loss. This type can also show up when people have a repetitive, unstimulating schedule, do not feel challenged, or feel stuck, overworked, or burned out. Situational apathy is typically temporary and may resolve on its own or with lifestyle changes^[14].

Psychological or persistent apathy is when apathy seems to have no external cause and is chronic and severe. In the fields of psychiatry and psychology, apathy usually describes emotional detachment and a reduced ability to experience pleasure, known as anhedonia. It typically does not include a lack of motivation to do activities or daily tasks, as the neurological definition does. People may experience episodes of apathy with certain psychological conditions, such as major depression and schizophrenia^[1][6].

People who experience traumatic events may develop apathy syndrome as a way to protect themselves mentally and prevent further distress. This is common in survivors of catastrophes or prisoners of war and can be part of post-traumatic stress disorder (PTSD)^[1].

Research has also identified three subtypes based on what aspect of life is most affected: behavioral apathy (related to actions and productivity), emotional apathy (related to feelings), and social apathy (related to interactions with others)^[2].

Causes and Brain Changes

Researchers have found that severe or chronic apathy typically results from damage to specific parts of the brain^[1]. Two critical brain regions are involved with apathy: the dorsal anterior cingulate cortex (a region that helps with cognition and movement control) and the ventral striatum (a part of the brain that plays a large role in social behaviors). It likely also involves other areas of the front and middle of the brain. The frontal lobe is also crucial^[1][6].

Together, these regions of the brain are crucial in processing how rewards motivate behaviors. When these networks are disrupted, there is a mismatch between motivation and reward or drive, leading to unwillingness to work or a lack of concern or sense of purpose. A decreased metabolism within the striatum is strongly associated with an increase in apathy^[8].

Dopamine is the primary neurotransmitter involved in these brain circuits and is heavily involved in regulating motivation. The basal ganglia, of which the striatum is a part, are involved in rewards or drive. The orbitofrontal cortex within the prefrontal cortex integrates networks from the striatum to give us a representation of the value of a behavior or reward^[8].

Related Medical Conditions

Apathy is a common symptom in multiple disorders. It has been described in^[4][5]:

• Alzheimer’s disease
• Parkinson’s disease
• Frontotemporal dementia
• Vascular dementia
• Huntington’s disease
• Major depressive disorder
• Schizophrenia
• Bipolar disorder
• Cerebrovascular disease
• Stroke
• Traumatic brain injury
• Progressive supranuclear palsy

Apathy is one of the most common symptoms of Alzheimer’s disease, affecting about 49% of people with the condition. In Parkinson’s disease, apathy rates can range from 25% in the earlier stages to 60% as the disease worsens^[1]. A large population-based study found apathy to be highly prevalent at 31.9% among people with cognitive impairment. The same study found it to be persistent and disabling^[4].

As a symptom, the prevalence of apathy in disorders that directly involve the cortex is 60%, and disorders of subcortical structures develop apathy at a 40% rate^[4].

Apathy has also been described in healthy individuals with an estimated prevalence of 1.45% in young subjects with reduced quality of life, and it shows patterns of increasing with age, especially in persons above the age of 65^[4].

Diagnosis and Assessment

Diagnosing apathy can be challenging because it frequently coexists with other conditions. Healthcare professionals are mindful of an individual’s medical history and mental health concerns when diagnosing or treating apathy^[7].

Several assessment tools have been developed to measure apathy clinically:

The Apathy Evaluation Scale is one standardized tool used by clinicians to assess the presence and severity of apathy^[5].

The Apathy Motivation Index was developed by researchers to help identify three subtypes of apathy: behavioral, emotional, and social^[2][5].

The Dimensional Apathy Scale is another tool that helps evaluate different dimensions of apathetic symptoms^[5].

A mental health professional will use various assessment tools and techniques to measure apathy and find out what is underneath it. They may ask questions to help identify triggers, such as what was happening in a person’s life just before they started feeling apathetic, what parts of life make them feel most numb, and whether the apathy affects all aspects of life or specific situations^[14].

Treatment and Management

While there is no direct treatment for apathy itself, certain approaches may help improve symptoms^[1]. Apathy is highly prevalent, disabling, and treatment-resistant, so the focus is typically on management rather than cure^[4].

Currently, there are no proven effective pharmaceutical treatments specifically for apathy. However, structured activities and opportunities for socialization are a useful approach. A regular routine, continuing to socialize, and exercising even when lacking motivation can help combat apathetic feelings^[13].

For situational apathy, these strategies may be helpful^[14]:

• Identifying what triggers the apathy and working to change reactions to those triggers
• Making lifestyle changes, such as trying new activities that challenge or fulfill in different ways—a new hobby, exercise routine, or making new friends
• Trying changes at work or school if those environments are causing the apathy
• Setting small, achievable goals to create a sense of purpose
• Focusing on what can be changed rather than what is beyond control
• Asking for help from trusted friends, family, or professionals

If apathy is affecting daily life persistently, talking to a therapist can help. A provider can help uncover the source of apathy and take steps to manage it. Treatment typically focuses on addressing any underlying conditions that may be causing the apathy, such as depression, Alzheimer’s disease, or Parkinson’s disease^[6].

Apathy can be frustrating for people experiencing it, their care partners, and loved ones. Understanding apathy as a symptom of an underlying condition and finding ways to cope with it are key to ensuring a good quality of life and maintaining good relationships^[13]. Apathy has been associated with functional decline, caregiver burden, increased cost of care due to early institutionalization, and increased mortality, making proper management important^[4].
