Final Answer:
The category of major depressive disorder in which the person experiences excessive activity or immobility is catatonic, thus the correct option is B.
Step-by-step explanation:
Catatonic features in major depressive disorder involve disturbances in motor behavior. This can manifest as either excessive activity or immobility. Excessive activity may include purposeless movements or even agitation, while immobility can involve maintaining a rigid posture for extended periods. These catatonic features are considered severe and can significantly impact the individual's daily functioning.
It's important to note that major depressive disorder can present in various ways, and the inclusion of catatonic features helps to capture the diversity of symptoms within this mental health condition. The term "catatonia" broadly refers to a range of psychomotor symptoms, and its presence in major depressive disorder signifies a more complex and severe manifestation of the illness.
Diagnosing and understanding the specific features of major depressive disorder, such as catatonia, is crucial for tailoring appropriate treatment interventions. In cases where catatonic features are prominent, a comprehensive approach that may include medication, psychotherapy, and supportive care is often recommended. The recognition of catatonic symptoms aids mental health professionals in providing targeted and effective support to individuals experiencing major depressive disorder with this particular presentation.
