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.

CADASIL has been reported notably in Europe, has recently been found to occur in Japan and, with the increase in the number of reported cases, has been attracting attention. Currently, the diagnosis of CADASIL is established clinically if the patient: (1) develops the condition at a relatively young age (40-50 years), (2) is not at risk for stroke, (3) has repeated attacks of lacunar infarction with gradual progression to pseudobulbar paralysis and dementia, and (4) has other family members with similar symptoms. The diagnosis is also established by imaging and laboratory studies if: (1) MRI reveals leukoaraiosis and multiple small infarcts in the deep white matter, basal ganglia, thalamus, and pons, with hyperintensities of the temporal pole and external capsule bilaterally; (2) electron microscopy demonstrates granular osmiophilic material (GOM) around vascular smooth muscles in the brain, skeletal muscle, and skin; and (3) DNA analysis shows notch3 mutations. The mechanism of development of CADASIL due to notch3 mutations is still unknown. However, a recent study revealed that Notch3 ectodomain is a major component of GOM. On binding to the ligand, Notch3 normally undergoes proteolytic cleavage, with the resulting clearance of the extracellular domain. However, in CADASIL, it accumulates as GOM and potentially inhibits normal metabolism in smooth muscle cells. It is necessary to suppress the production of GOM for fundamental therapy of CADASIL.

Vascular dementia (VaD) is the second most frequent dementia after Alzheimer's disease, and is diagnosed during lifetime in 20% of demented patients. Five-year survival rate in VaD is 39%, while it is estimated to be 75% in healthy persons of the same age. It is therefore important to make correct diagnosis of VaD early in the course of the disease. Risk factors forVaD are identical to stroke risk factors, and there are significant possibilities for the prevention of vascular cognitive decline. Cognitive decline develops acutely or step-by-step within three months after stroke, but more gradual progression of intellectual decline is also possible. Neurological examination can reveal pyramidal and extrapyramidal signs, pseudobulbar palsy, gait disturbance and urinary incontinence. Neuropsychological profile comprises the loss of cognitive set shifting, decline in word fluency, verbal learning difficulties, perseverations, difficulties in complex figure copying, and in patients with cortically located lesions also problems with speech and praxia. The basis of the diagnosis is, besides history, neurological examination and neuropsychological assessment, computed tomography and/ or magnetic resonance brain imaging. Vascular risk factors control is the most important measure in VaD prevention. Modern guidelines for the treatment of cognitive decline in VaD emphasize that donepezil can be useful in the improvement of cognitive status at the level of Class Ila recommendation at the level of evidence A, while memantine may be useful in patients with mixed VaD and Alzheimer's disease dementia.

Cosimo I de' Medici (1519-1574) was the first Grand Duke of Tuscany. He was one of the most important members of the Medici family. He was an excellent conqueror and a good politician. Moreover, he was able to attract and encourage artists, scientists and architects to promote Florence as the cultural capital of the Italian Renaissance. Historical chronicles report that he suffered from a stroke when he was 49 years old. Together with the acute manifestation of stroke, he displayed peculiar symptoms. He had gait disturbances and sphincter dysfunctions. His language became poor and hard to understand. His mood was very fluctuating and in the last years of his life he was a short-tempered man. In addition, he had a characteristic symptom, so-called pathological laughing and crying. The course of his disease was slow and stuttering. Taken together, these data seem to be one of the first reports of pseudobulbar paralysis. The disease of Cosimo I was probably due to a chronic cerebral vasculopathy, known as small vessels disease. We discuss this hypothesis regarding an ancient clinical case, with the support of current studies.

A 55-year-old woman was admitted with a 3 days history of increasing lethargy with bradyphrenia and apathy. She progressively developed severe somnolence with marked abulia, right hemiparesis, right hemianopsia, and pseudobulbar palsy. Brain magnetic resonance imaging showed the rare image of bilateral acute anterior choroidal artery infarction. Pseudobulbar mutism and in rare cases abulia have been described in acute anterior choroidal artery infarction contralateral to an older lesion in mirror position. Although neurologic deterioration is not infrequent in anterior choroidal artery territory infarcts, the absence of focal neurologic signs on admission is rare and did not raise suspicion of acute stroke.

The quality of guidelines of clinical practice in acupuncture and moxibustion was evaluated with AGREE II tool. After retrieval of officially-issued guidelines of clinical practice in acupuncture and moxibustion from 2004 to 2013, totally 5 types of evidence-based guidelines of clinical practice in acupuncture and moxibustion were acquired, including depression, herpes zoster, pseudobulbar palsy after stroke, migraine and Bell's palsy. With AGREE II tool, independent score in six areas, including guideline's scope and purpose, participants and personnel, preciseness, clarity and readability, applicability and editorial independence were analyzed to perform a comprehensive evaluation in the end. The assessment results indicated that the score of editorial independence in evidence-based guidelines of clinical practice in acupuncture and moxibustion was the highest, averagely 97.9%, which was followed by clarity and readability (83.3%), participants and personnel (78.1%), preciseness (75.6%), the scope and purpose (68.1%) and the applicability (62.5%). The total evaluation score was all 6 points in the five guidelines with recommended as comprehensive evaluation advice. This study results indicate that although the guideline of clinical practice in acupuncture and moxibustion is low in number, the total quality is considerable.

Tongguan Liqiao acupuncture therapy has been shown to effectively treat dysphagia after stroke-based pseudobulbar paralysis. We presumed that this therapy would be effective for dysphagia after bulbar paralysis in patients with brainstem infarction. Sixty-four patients with dysphagia following brainstem infarction were recruited and divided into a medulla oblongata infarction group (n = 22), a midbrain and pons infarction group (n = 16), and a multiple cerebral infarction group (n = 26) according to their magnetic resonance imaging results. All patients received Tongguan Liqiao acupuncture for 28 days. The main acupoints were Neiguan (PC6), Renzhong (DU26), Sanyinjiao (SP6), Fengchi (GB20), Wangu (GB12), and Yifeng (SJ17). Furthermore, the posterior pharyngeal wall was pricked. Before and after treatment, patient swallowing functions were evaluated with the Kubota Water Test, Fujishima Ichiro Rating Scale, and the Standard Swallowing Assessment. The Barthel Index was also used to evaluate their quality of life. Results showed that after 28 days of treatment, scores on the Kubota Water Test and Standard Swallowing Assessment had decreased, but scores on the Fujishima Ichiro Rating Scale and Barthel Index had increased in each group. The total efficacy rate was 92.2% after treatment, and was most obvious in patients with medulla oblongata infarction (95.9%). These findings suggest that Tongguan Liqiao acupuncture therapy can repair the connection of upper motor neurons to the medulla oblongata motor nucleus, promote the recovery of brainstem infarction, and improve patient's swallowing ability and quality of life.

Bilateral paramedian thalamic infarction is a rare subtype of stroke caused by occlusion of the artery of Percheron, an uncommon variant originating from one of the posterior cerebral arteries. This type of stroke has several major clinical presentations: altered mental status, behavioral amnestic impairment, aphasia or dysarthria, ocular movement disorders, motor deficits, cerebellar signs, and others. Few cases of bilateral paramedian thalamic infarction-related pseudobulbar palsy characterized by dysarthria, dysphagia, and facial and tongue weakness have been reported. We report here a rare case of acute severe pseudobulbar palsy as a manifestation of bilateral paramedian thalamic infarction.

Foix-Chavany-Marie syndrome, which has been reported since the 19th century, is a cortical type of pseudobulbar palsy. Although previously most cases were due to acute recurrent stroke, recent reports have indicated that there are various causes, including infectious, developmental, epileptic and degenerative processes and various clinical courses, which may be transient or slowly progressive. Moreover, modern imaging techniques have revealed the significance of the injury of the white matter tract, such as the frontal aslant tract, rather than classical lesions of bilateral motor cortices. Considering both the findings of the bedside examination of patients with this "old" syndrome and of "new" imaging studies performed at appropriate times is expected to contribute to our understanding of the neural underpinnings of this syndrome.
