of progression or relapse induction and consolidation therapy should be restarted. Our patient demonstrated neither relapse nor progression but presented with a novel disease complication of acute fluctuating neurology in chronic stable cryptococcomas.
Carotid free-floating thrombus (FFT) is an unusual finding in acute ischemic stroke. Atherosclerosis is the most common etiology of FFT formation.
Here we report a 42-year-old male patient admitted to our department with left temporal and parietal lobe ischemic stroke with normal magnetic resonance angiography. A huge FFT in the left internal carotid artery were found by duplex ultrasound. Acute thrombosis based on atherosclerotic plaque were considered as the reason of this embolization. The thrombus shrunk significantly under anticoagulation and antiplatelet treatment.
Evaluation of the intracranial vessel in the emergency is not enough and early carotid duplex ultrasound can help find of the FFT in time, which help to choose the early intervene by neurosurgeon. Early antithrombotic treatment can be a safe treatment option for reducing huge thrombus based on the nature of thrombus formation. Computed tomography angiography and high-resolution magnetic resonance imaging to certify the character of the plaque are recommended for plaque evaluation.

Phenylketonuria (PKU) is the most common inborn error of amino acid metabolism and causes neurological manifestations because of excessive accumulation of phenylalanine (PHE). It can also affect adult patients who discontinue their treatment, even if they had been under adequate metabolic control during childhood. For that reason, it is recommended that PKU treatment should be continued throughout life and target PHE levels for adult patients should range between 120 and 600 μmol/L.
The authors present an adult patient with PKU who discontinued treatment and developed cognitive dysfunction because of high blood levels of PHE. Brain magnetic resonance imaging (MRI) of the patient was characteristic for PKU, presenting periventricular and callosal white matter hyperintensities in T2 and fluid-attenuated inversion recovery sequences, which were additionally associated with true restriction in diffusion-weighted imaging sequence, a far less recognized PKU neuroimaging feature.
Cognitive dysfunction and psycribed neuroimaging feature of PKU, but diffusion-weighted imaging sequence may also be reliable in detecting brain lesions in patients with PKU. PKU lesions should be considered in the differential diagnosis of true diffusion restriction in brain MRI of patients with PKU history or those who might have escaped newborn screening diagnosis but present neurocognitive dysfunction. Appropriate treatment for the management of PKU should be initiated for the reversal of the clinical and neuroimaging findings.
Coronavirus disease 2019 (COVID-19) pandemic started as an outbreak in China and soon crossed borders to affect the populations in all countries of the world. During the initial course of the disease, COVID-19 was perceived as a pneumonia-like illness. However, recent findings of COVID-19 patients suggest that the virus has the potential to disseminate to different tissues and organs, and cause significant complications.
Neurological symptoms are of great significance as these usually present in and complicate critical cases. Many case reports and case series have documented the findings of neurological complications in COVID-19 patients. From the existing data, the most frequent symptoms in these patients were broadly classified into the central nervous system (CNS), peripheral nervous system, and skeletal muscular symptoms. CNS symptoms include meningitis, encephalitis, cerebrovascular complications, peripheral nervous system symptoms include anosmia, ageusia, and skeletal muscular symptoms include myalrum of clinical manifestations, radiologic findings, and likely mechanisms of injury. Understanding the symptoms and radiologic imaging allows clinicians to consider brain imaging in any patient with suspected COVID-19 and neurological symptoms.
To assess the stroke awareness levels of individuals whose first-degree relatives had a stroke and to compare the results with those of individuals whose first-degree relatives did not have a stroke.
This cross-sectional study was conducted between March and May 2019, with first-degree relatives of patients who had a stroke (group 1) and a comparable set of individuals whose first-degree relatives did not have a stroke (group 2). Participants were asked to complete a questionnaire asking about signs and symptoms, risk factors, treatment options, information sources, responses after the development of stroke, and early treatment of stroke.
In response to the questions about the signs and symptoms of stroke, group 1 mentioned dizziness and comprehension disorder as a symptom of stroke more frequently than the other group. read more Stress was the second most frequently mentioned risk factor (by 81% of group 1 and 80.5% in group 2). When the participants were asked about the sources of information about stroke, family circle and friends were the most frequently mentioned sources for both groups.
The present study can serve as a guide in planning training to improve stroke awareness in the future, especially by including individuals whose first-degree relatives had a stroke.

To observe the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with nonfluent aphasia after stroke.
Thirty patients were divided into control, rTMS, and 2 times a day low-frequency rTMS (2rTMS) groups, and all 3 groups had intensive speech therapy (ST). Patients were assessed by western aphasia battery (WAB) scale. The spontaneous language, listening comprehension, retelling, and naming were scored, respectively. The expression of brain-derived neurotrophic factor (BDNF) in peripheral blood was detected by enzyme-linked immunosorbent assay.
There was significant difference in aphasia quotient after treatment in the 3 groups. The values of the 4 dimensions in the WAB score of the rTMS group were higher than those in the control group. The WAB scores in the 2rTMS group were higher than those in the rTMS group. After 2 weeks treatment, the BDNF levels in the rTMS group and the 2rTMS group were significantly higher than those in the control group. Four weeks later, the 2rTMS group was significantly increased compared with the control group and the rTMS group.read more
