Ø    Clinical symptoms: Disheartened mood, gloominess, dreariness, pessimism, diurnal mood variation, anergia, weight loss, early-morning awakening

Ø    Associated lesion location: Left frontal lobe and left basal ganglia during the acute period after stroke

Ø    Treatment: Pamelor: proved effective in randomized placebo-controlled dbl studies

MINOR DEPRESSION

Ø    Prevalence: 10-40% of patients with cerebrovascular disease

Ø    Clinical symptoms: Lugubrious mood, disinclined to social interaction, decreased appetite, uneasiness, disquiet

Ø    Associated lesion location: Left posterior parietal and occipital regions during the acute poststroke period

Ø    Treatment: No controlled studies. SSRIs perhaps???

APATHY

Ø    Prevalence: 22% of patients with cerebrovascular disease

Ø    Clinical symptoms: Anhedonia, doleful demeanor, ennui, languor

Ø    Treatment: No controlled studies. Cognitive Behavior Therapy, perhaps???

MANIA

Ø    Prevalence: Rare

Ø    Clinical symptoms: Grandiloquent mood, libertine appetites, magniloquent well-being

Ø    Associated lesion location: Right basotemporal or right orbitofrontal lesions

ANXIETY DISORDER

Ø    Prevalence: 27% of patients with cerebrovascular disease

Ø    Clinical symptoms: Apprehensive dread, restiveness, insomnia, fretfulness, angst

Ø    Associated lesion location: Left cortical lesions, usually dorsolateral frontal lobe

Ø    Treatment: Avoid benzodiazepines because they impair cognition

CATASTROPHIC REACTION

Ø    Prevalence: 19% of patients with cerebrovascular disease

Ø    Clinical symptoms: Choleric agitation, strident acrimony, bellicosity, vitriolic brooding, menacing intimidation, obstreperous attitude, scurrilous vocabulary

Ø    Associated lesion location: Left anterior-subcortical region

Ø    Treatment: No studies. Depakote, perhaps???
