Flat affect indicates the diminished expression of emotion. While people with flat affect still experience emotion, they are unable to express emotions in typical and expected physical ways. They exhibit a lack of response to emotional stimuli such as reduced or absent facial expressions, monotone voice, and difficulty understanding the emotions of other people.

This extremely limited range of expressions occurs even in situations that would normally seem very exciting or very sad. For instance, upon hearing the great news, someone withschizophreniamay not smile, laugh, or have any joy in their response.

Flat affect is more common among men than women and is often present during the onset of schizophrenia.

Causes of Flat Affect

More often than not, flat affect is an underlying symptom of several conditions—not just schizophrenia. It may even be a side-effect of certain medications, includingantidepressants. Muscle disorders or facial paralysis, such ascatalepsyand Bell’s palsy,can also make it difficult to express emotions.

It’s important to note that while you may have trouble displayingemotion, many people with schizophrenia have no difficulty recognizing emotional responses in others. This is an important factor in working with your doctor to define a treatment plan, as it gives you a foundation to build on to create appropriate social exchanges.

Treatment for Flat Affect

Flat affect can be treated to some degree. It often requires comprehensive therapy, including working with a healthcare provider and taking medication. While it often cannot be completely eliminated, therapy and intervention can help you interact with others more warmly and naturally and get your other symptoms of schizophrenia under control.

Therapy and Intervention

Cognitive behavioral therapy, or CBT, is one of the most researched models of therapy used in the treatment of schizophrenia. CBT can help people with flat affect begin to recognize how their emotionless response does not match what is required in a specific situation.

Your therapist may have you practice appropriate reactions to different stimuli (like grief or celebration) so that you can learn how to react as other people do.

How Behavioral Therapy Works

Medication

The newer “atypical” antipsychotics also influence other neurotransmitters in the brain and may help with a flat affect. Clozaril (clozapine) is one of these agents shown to help combat flat affect in people with schizophrenia and other mental illnesses for which this is a concern.

Coping and Support for Caregivers

Caring for a loved one who is suffering from flat affect is challenging. It’s much more than dealing with a loved one who tends to be “cold.” It’s not a personality trait. This symptom of schizophrenia makes it impossible for your loved one to translate emotion into a verbal or physical expression. The brain and body are not connecting.

While they may be unable to express their emotions, your emotions are likely in overdrive as you struggle to come to terms with this symptom of schizophrenia. Continuing to educate yourself on the condition and the experiences your loved one will face is one of the most important ways to cope.

Gathering information can help you better understand what to expect and what you can do to help.

Although your primary focus is on supporting your loved one, it’s also important to remember to help yourself. This means seeking support from local or online groups, a mental health provider, or a trusted friend or family member.

Sharing your experiences and challenges can help you process your emotions and give you encouragement and hope. You may also gain helpful information about new or progressive treatment methods as well as other resources to help your loved one.
