Catatonia, classified as a psychomotor syndrome, is a fascinating neurological disorder that impacts around 10% of individuals with acute psychiatric conditions. While many associate catatonia with a complete absence of movement or brain activity, it is important to note that there is another form known as excited catatonia, which manifests as restlessness and agitation.
Akinetic Catatonia: The Inability to Move Voluntarily
Akinetic catatonia, also known as akinesia, refers to the condition where individuals are unable to move voluntarily. This form of catatonia is characterized by catalepsy, which involves body rigidity and a complete lack of movement. Additionally, individuals with akinetic catatonia may also experience a complete inability or refusal to speak.
Research and tests have shown that individuals suffering from akinetic catatonia exhibit significantly less activity in the medial prefrontal cortex. This region of the brain is responsible for social cognition, which plays a crucial role in our ability to understand and interact with others.
Understanding Excited Catatonia
Excited catatonia is a condition characterized by disorientation and confusion in individuals. These individuals exhibit bizarre and flighty ideas, often expressing themselves in an abrupt manner. They may frequently repeat meaningless random words and phrases, which can sound forced. In some cases, they may also imitate the movements and speech of others, a phenomenon known as echopraxia and echolalia, respectively. It is not uncommon for individuals with excited catatonia to exhibit combative behavior towards those in their surroundings.
