Lennox-Gastaut Syndrome is characterized by a triad of symptoms: multiple seizure types, a specific EEG pattern (slow spike-and-wave activity), and cognitive impairment. The seizure types commonly seen in this syndrome include atonic seizures, tonic seizures, and atypical absence seizures.

Atonic seizures are known for causing a sudden loss of muscle tone, leading to falls. Tonic seizures involve muscle stiffness and can cause postural changes. Atypical absence seizures present as brief episodes of impaired awareness, often with different clinical manifestations than typical absence seizures.

Complex seizures, however, do not specifically describe a recognized seizure type associated with Lennox-Gastaut Syndrome. The term "complex seizure" often refers to complex partial seizures or focal seizures with impaired awareness, which are not hallmark features of this syndrome. Hence, complex seizures do not fit within the primary classification of seizures seen in affected individuals. Understanding this distinction clarifies why complex seizures are not typically associated with Lennox-Gastaut Syndrome.
