Catatonia

Catatonia, a complex neuropsychiatric syndrome, is often misunderstood and misdiagnosed. This condition, which is marked by abnormalities in movement and behaviour, can severely impact an individual's quality of life.

What is Catatonia?

Catatonia is characterized by a range of motor, behavioural, and affective abnormalities. It can manifest as an inability to move, unusual movements, and resistance to movement. In some cases, individuals may exhibit excessive motor activity, which is purposeless and not influenced by external stimuli.

Catatonia has been recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and is classified under the ICD-10 code F06.1. It is often associated with psychiatric conditions such as schizophrenia, bipolar disorder, and major depressive disorder but can also occur in medical conditions, including neurological disorders and systemic illnesses.

Symptoms of Catatonia

The symptoms of catatonia are varied and can be broadly categorized into three types: retarded, excited, and malignant. Each presents its own unique challenges and requires tailored treatment approaches.

Retarded Catatonia

Retarded catatonia is marked by a significant decrease in motor activity. Symptoms include:

Excited Catatonia

Excited catatonia, in contrast, involves excessive motor activity and agitation. Symptoms include:

Malignant Catatonia

Malignant catatonia, also known as lethal catatonia, is a life-threatening condition characterized by:

Diagnosing Catatonia

The diagnosis of catatonia is primarily clinical and based on the observation of characteristic symptoms. The use of standardized assessment tools, such as the Bush-Francis Catatonia Rating Scale (BFCRS), can aid in the diagnosis. This scale assesses the presence and severity of catatonic symptoms.

Additionally, it is crucial to identify and address any underlying conditions that may contribute to catatonia. This requires a comprehensive assessment, including medical history, physical examination, and relevant laboratory tests.

Treatments for Catatonia

Effective treatment of catatonia requires a multidisciplinary approach, often involving psychiatrists, neurologists, and other healthcare professionals. Treatment strategies are tailored to the type and severity of catatonia and may include pharmacological and non-pharmacological interventions.

Pharmacological Treatments

Benzodiazepines

Benzodiazepines, particularly lorazepam, are considered the first-line treatment for catatonia. They work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA), which has a calming effect on the brain. Lorazepam is typically administered in high doses, and response to treatment is often rapid, with symptoms improving within hours to days.

Electroconvulsive Therapy (ECT)

ECT is a highly effective treatment for catatonia, especially in cases where benzodiazepines are ineffective or contraindicated. ECT involves the application of electrical currents to the brain under general anaesthesia, inducing a brief seizure. This treatment can result in significant improvements in catatonic symptoms.

Antipsychotics

Antipsychotic medications may be used in cases where catatonia is associated with psychotic disorders. However, caution is advised, as some antipsychotics can exacerbate catatonic symptoms.

Non-Pharmacological Treatments

In addition to pharmacological treatments, non-pharmacological approaches can also be beneficial.

Supportive Care

Supportive care is essential in managing catatonia, particularly in severe cases. This includes ensuring adequate hydration and nutrition, preventing complications such as pressure sores and infections, and providing a safe environment.

Physical Therapy

Physical therapy can help improve mobility and prevent complications associated with immobility. Techniques such as passive range-of-motion exercises can be beneficial.

Psychotherapy

Psychotherapy, particularly cognitive-behavioural therapy (CBT), can be useful in addressing the psychological aspects of catatonia. It can help individuals develop coping strategies and improve their overall functioning.
