Depression and apathy are often observed after stroke and are often confused with one another. In the present review, we argue that the current concept of 'post-stroke depression' (PSD) in fact consists of two core symptoms or syndromes: (i) affective (depressive) PSD; and (ii) apathetic PSD. We argue that these two core symptoms are each associated with a different underlying neuroanatomical mechanism, a pattern that influences functional recovery. Post-stroke disabilities can provoke several distinct emotional responses, some of which are associated with severe depression. We examined one of these emotional responses previously, namely 'insistence on recovery', which was believed to be a negative indicator of functional improvement in disabled stroke patients. However, an appropriate level of insistence on recovery may, in fact, be associated with reduced depression and apathy, resulting in enhanced recovery from stroke-related disabilities. Improvements in physical disabilities (trunk stability or activities of daily living, such as walking) also reduce depression and apathy. Therefore, the experience of PSD/apathy may be intertwined with various initial emotional responses and improvements in physical functioning. Effective treatment of PSD/apathy requires a multidisciplinary approach, such that neuroanatomical/neurobiological, emotional, and physical (rehabilitation) domains are all addressed.

Few studies have reported neuropsychiatric symptoms (NPS) in primary progressive aphasia (PPA), a neurodegenerative disorder that primarily affects the left hemisphere. Depression is associated with left-sided stroke, but it remains unclear whether depression and other NPS are also associated with PPA. The authors compared the frequency of neuropsychiatric symptoms in 55 cases of PPA with 110 cognitively normal persons matched for age, sex, and education. Depression, apathy, agitation, anxiety, appetite change, and irritability are associated with PPA. Hallucinations, delusions, and night-time behavior were not associated with PPA.

Dysthymia is a depressive mood disorder characterized by chronic and persistent but mild depression. It is often difficult to be distinguished from major depression, specifically in its partially remitted state because "loss of interest" or "apathy" tends to prevail both in dysthymia, and remitted depression. Apathy may also occur in various psychiatric and neurological disorders, including schizophrenia, stroke, Parkinson's disease, progressive supranuclear palsy, Huntington's disease, and dementias such as Alzheimer's disease, vascular dementia, and frontotemporal dementia. It is symptomatologically important that apathy is related to, but different from, major depression from the viewpoint of its causes and treatment. Antidepressants, especially noradrenergic agents, are useful for depression-related apathy. However, selective serotonin reuptake inhibitors (SSRIs) may be less effective for apathy in depressed elderly patients and have even been reported to worsen apathy. Dopaminergic agonists seem to be effective for apathy. Acetylcholine esterase inhibitors, methylphenidate, atypical antipsychotics, nicergoline, and cilostazol are another choice. Medication choice should be determined according to the background and underlying etiology of the targeting disease.

Early recognition of psychopathological symptoms (PSs) after stroke is important because they greatly influence the recovery of patients. The aim of this study was to investigate the predictive factors of PSs occurring in patients with ischemic stroke. Eighty-nine patients were prospectively evaluated upon admission and 4, 12, and 26 weeks later with the Neuropsychiatric Inventory, Hamilton's Rating Scales for Depression and Anxiety, and a battery of neuropsychological and functional scales. Depression and apathy were the most frequent PSs detected after stroke. Premorbid psychopathologies and right-hemisphere location were the main predictive indicators of early and long-term PSs.

Depression is the most common neuropsychiatric complication of a stroke (Post Stroke DepressionPSD) and has been shown to impede the recovery and rehabilitation of these patients. Prevalence rates of PSD vary between 6% and 79%. Direct comparison between studies is limited due to their different methodology. Etiology of PSD is determined by biological and psychosocial factors. Symptoms of PSD appear in three areas: affective, somatic and cognitive. Differential diagnosis includes post-stroke fatigue and pseudo-depressive manifestations of ischemic infarctions (apathy, aprosody, athymhormia, pseudobulbar palsy). Mortality in post-stroke patients is higher than in non-depressed stroke patients and suicide ideation is observed in 6.6-11.3% of stroke patients. Selective serotonin reuptake inhibitors (SSRI) are considered as the first choice treatment of PSD. Other therapeutic approaches include cognitive and functional rehabilitation. PSD is a potentially treatable condition, yet under-diagnosed, and has a negative effect on functional recovery and survival of stroke patients.

Psychiatric syndromes are common in the patients with cerebrovascular disease. Poststroke depression (PSD) is a most frequent complication of after cerebrovascular disease. Depression affects 20-50% of patients within a year after stroke. PSD has a negative impact on functional recovery. Poststroke anxiety disorder, apathy and pathological laughing and crying are also frequent and under-detected symptoms. In this chapter, we described an outline mainly on treatment of PSD among these symptoms, in paticular, about antidepressant medications. There is an association between depression and atherosclerosis. Several trials have shown evidence that antidepressants may prevent depressive symptoms after stroke. The concept of "vascular depression" will suggest that the establishment of a new treatment strategy is demanded in future.

CADASIL (cerebral arteriopathy, autosomal dominant, with subcortical infarcts and leu-koencephalopathy) is an infrequent inherited disease that could have anesthetic implica-tions. However these have rarely been reported. We present a male patient previously diagnosed with CADASIL, who had suffered an ischemic vascular cerebral accident with a MRI compatible with leukoencephalopathy, and who was dependent for daily activities, and sustained dementia, mood alterations, apathy, and urine incontinence. He had famil-ial antecedents of psychiatric symptoms and ischemic stroke events in several relatives including his father, two brothers and one sister. He was scheduled for arthrodesis of the left knee because of multiple infectious complications of prosthetic knee surgery. He was under clopidogrel treatment which was withdrawn seven days before surgery. The pro-cedure was performed under combined spinal-epidural anesthesia, intraoperative seda-tion with midazolam, and postoperative multimodal analgesia including epidural patient controlled analgesia. The perioperative management was uneventful and we outline the adequacy of managing these patients under regional anesthesia and analgesia, as these permit to maintain hemodynamic stability leading to adequate cerebral perfusion, key to avoid an increase in the effects of the chronic arteriopathy patients with CADASIL sustain.

Neurological and psychiatric aspects of emotions have been the focus of intense research for the past 30 years. Studies in both acute (e.g., stroke, traumatic brain injury (TBI)) and chronic (e.g., dementia, Parkinson's disease) neurological disorders demonstrated a high frequency of both depression and apathy. Studies in stroke and TBI reported a significant association between lesion location and depression. Both depression and apathy are significant predictors of poor recovery among patients with brain injuries, and of steeper cognitive and functional decline among patients with neurodegenerative disorders. Poor insight and judgment are frequently found among patients with brain injury or degeneration. There is increasing evidence that damage to specific brain regions, such as the ventromedial prefrontal cortex, is associated with inappropriate emotional reactions in social contexts and diminished anxiety and concern for the future. In severe cases, behavioural changes may also include poor decision-making in the social realm, deficits in goal-directed behavior, and lack of insight into these changes. Future studies will validate specific diagnostic criteria for the various cognitive, emotional, and behavioral problems reported among patients with neurological disorders, which may result in more specific and effective treatments.

Apathy is a common clinical feature of stroke patients and it is often correlated with cognitive deficits, functional impairment and depression. Here we report the case of a 70-year-old woman with no history of neuropsychiatric disorders who showed abrupt onset of pure apathy after the onset of a right brain vascular lesion located in the head of the caudate nucleus, the anterior part of the putamen, and the genu and the anterior limb of the internal capsule. A complete neuropsychological and neurological examination did not show deficits. A comprehensive neuropsychiatric assessment focusing on the post-stroke hospitalization period showed severe motor, cognitive and affective apathy with no depression or other neuropsychiatric symptoms. This case highlights the key role of the dorsal striatum in the development of pure apathy, possibly due to its function in regulating approach-attachment behavior, affect and initiative, which are the emotional, cognitive and motor dimensions of apathy.

Strategic regions correspond to associative, limbic and paralimbic structures and related circuits, that underpin cognitive/behavioral functions. Strokes in these eloquent sites produce pictures of vascular dementia with syndromic features due to specific site lesion and/or interruption of their interconnections. This study aims at analysing subcortical strategic strokes that express similar cognitive/behavioral elements, by sharing common pathways. Patients (n=6) who attended in specialized ambulatory, were submitted to neuropsychological and neuroimaging assessments through MRI (GE Signa Horizon 1.5T) and brain SPECT (Millennium MG, ECD [TC-99m]). Stroke locations and respective main symptoms were: 1. anteromedian thalamus [L]: anterograde and retrograde amnesia (ARA), expression aphasia (EA), executive dysfunction (ED), apathy, and depression; 2. anterior thalamus [R]: ARA, inattention, apathy, and aggressiveness; 3. dorsomedian thalamus [L]: inattention, ED, anosognosia, and aggressiveness; 4. central paramedian thalamus [R]: EA, visual perception deficits (VPD), ED, infantility, and personality disorder; 5. caudate nucleus (ventral-head) [L]: VPD, ED, delirium, visual hallucinations, and personality disorder; and 6. anterior capsule [L]: VPD, ED, apathy, and depression. Vascular strategic syndromes connote the predominantly impaired cognitive/behavioral symptom of each site. Temporal and frontal disconnection symptoms were produced by disrupted MTT/hippocampal and IML/amygdala circuits expressing amnesic syndrome associated with heterogeneous dysexecutive syndrome, in all the cases, by disrupting frontal-basal ganglia-thalamus-cortical net, in three different levels of their pathway.
