What is the term for toxic levels of serotonin that can be dangerous?

Serotonin Syndrome is the term used to describe a potentially life-threatening condition that results from excessive levels of serotonin in the brain. This syndrome can occur after the use of certain medications, particularly those that increase serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), or other drugs that enhance serotonin activity.

In Serotonin Syndrome, a range of symptoms may manifest, including agitation, confusion, rapid heart rate, dilated pupils, muscle rigidity, and in severe cases, it can lead to seizures or even coma. The condition requires immediate medical attention, as it can escalate rapidly and lead to serious complications.

The other terms listed refer to different clinical phenomena. Akathisia refers to a state of inner restlessness and an uncontrollable need to be in constant motion, often associated with antipsychotic medications. Dystonia involves involuntary muscle contractions, leading to abnormal postures or movements, and is also often a side effect of antipsychotic medications. Tricyclic Antidepressants are a class of medications used to treat depression and other disorders but do not define the toxic condition associated with high serotonin levels.
