What is Neuropsychiatry — Frontal Lobe Syndromes?
Frontal lobe syndromes are a group of neuropsychiatric conditions resulting from damage or dysfunction of the prefrontal cortex and its connections. Three classical clinical syndromes are described: (1) dorsolateral prefrontal syndrome (dysexecutive) with impaired planning, working memory, and cognitive flexibility; (2) orbitofrontal syndrome with disinhibition, impulsivity, irritability, and emotional lability; and (3) medial frontal/anterior cingulate syndrome with apathy, abulia, and akinetic mutism in severe cases.
Causes include traumatic brain injury, stroke, frontotemporal dementia (behavioral variant), Alzheimer disease (later stages), brain tumors, multiple sclerosis, vasculitis, prion disease, neurosyphilis, HIV-associated neurocognitive disorder, and chronic alcohol use. Frontal networks have widespread connections, so distant lesions or subcortical damage (basal ganglia, thalamus) can mimic frontal syndromes.
Diagnosis combines neurologic exam, neuropsychological testing (Wisconsin Card Sorting, Stroop, Trail Making, Frontal Assessment Battery), brain MRI, FDG-PET, and laboratory workup for reversible causes. Treatment is symptom-focused: cognitive rehabilitation, behavior management, environmental modifications, and pharmacotherapy (SSRIs for impulsivity, dopaminergic agents for apathy, mood stabilizers, atypical antipsychotics with caution). Caregiver support and safety measures are essential.
