What Are the Classifications of Perinatal Stroke?
Discussion Perinatal stroke occurs in about 1:1000 live births and is a “focal vascular injury from the fetal period to 28 days postnatal age.” Perinatal stroke is the most common cause of hemiparetic cerebral palsy and causes other significant morbidity including cognitive deficits, learning disabilities, motor problems, sensory problems including visual and hearing disorders, epilepsy, and behavioral and psychological problems. Family members are also affected because of the potential anxiety and guilt feelings that having a child with a stroke presents, along with the care that may be needed over the child&#...

Neuroanatomical correlates of macrostructural receptive abilities in narrative discourse in unilateral left hemisphere stroke: A behavioural and voxel-based morphometry study
CONCLUSIONS & IMPLICATIONS: The present results suggest that retelling and comprehension of auditory and written narratives are relatively well-preserved in individuals with a LH stroke without significant aphasia, but poorer than in HC. The findings replicate previous studies conducted in groups with higher levels of education and SES both at the behavioural and neural levels. Considering that naming seems to be associated with narrative retell and comprehension in individuals with lower SES and education, this research provides evidence on the importance of pursuing further studies including larger samples with and witho...

Is This Primary Exertional Headache?
Discussion Commonly occurring primary headaches include tension, cluster and migraine headaches. “Other primary headaches” are often situational. Patients can have more than 1 type of these “other” headaches along with more common headaches. Other primary headaches as a group tend to be self-limited with long remission periods. Some other primary headaches include: Thunderclap headache Explosive sudden onset with maximum intensity in less 1 minute and resolution within 5 minutes usually 43/100,000 persons in adults Primary or secondary Secondary causes include intracranial hemorrhage, stroke, thro...

Association of Stroke and Cerebrovascular Pathologies With Scam Susceptibility in Older Adults
CONCLUSIONS AND RELEVANCE: Cerebrovascular pathologies, specifically cerebral infarcts, is linked with greater scam susceptibility in older adults, independent of common neurodegenerative diseases such as Alzheimer disease. Future studies examining in vivo magnetic resonance imaging markers of cerebrovascular pathologies with scam susceptibility and related decision-making outcomes will be important.PMID:36315115 | DOI:10.1001/jamaneurol.2022.3711

Concurrent TMS-fMRI: Technical Challenges, Developments, and Overview of Previous Studies
Transcranial magnetic stimulation (TMS) is a promising treatment modality for psychiatric and neurological disorders. Repetitive TMS (rTMS) is widely used for the treatment of psychiatric and neurological diseases, such as depression, motor stroke, and neuropathic pain. However, the underlying mechanisms of rTMS-mediated neuronal modulation are not fully understood. In this respect, concurrent or simultaneous TMS-fMRI, in which TMS is applied during functional magnetic resonance imaging (fMRI), is a viable tool to gain insights, as it enables an investigation of the immediate effects of TMS. Concurrent application of TMS d...

Polyuria, Polydipsia and Possible Diabetes Insipidus?
Discussion The body is smart. It has mechanisms for maintaining balances within the body in a closely controlled manner but allows for a variety of states. This is very true for fluid balance in the body which is highly controlled between almost all of the major body organ systems. When fluid is low, the sensor sends signals for us to drink, and conserves fluid until we can. When the fluid is high, the kidneys excrete the excess and sends signals not to drink. Usually it works very well. While there are many pathological states that can cause polyuria and/or polydipsia, the most common reason is excessive fluid intake beca...

Association of ankle-brachial index with cognitive decline in patients with lacunar infarction
This study aimed to investigate the relationship of ankle-brachial pressure index (ABI) and brachial-ankle pulse wave velocity (baPWV) with cognitive function in patients with lacunar infarction. We included records of consecutive patients with their first-ever acute stroke and a diagnosis of lacunar infarction through magnetic resonance imaging (MRI) from July 1, 2011 to December 31, 2018. We excluded patients diagnosed with dementia, including strategic single-infarct dementia, before or after stroke onset. Moreover, we excluded patients with one or more microbleeds, severe white matter lesions, or severe medial temporal...

Elevated Aortic Pulse Wave Velocity Relates to Longitudinal Gray and White Matter Changes
CONCLUSIONS: In older adults, higher baseline aortic PWV related to greater decrease in gray matter volume and greater increase in WMHs over time. Because of unmet cerebral metabolic demands and microvascular remodeling, arterial stiffening may preferentially affect certain highly active brain regions like the temporal lobes. These same regions are affected early in the course of Alzheimer disease.PMID:34706559 | DOI:10.1161/ATVBAHA.121.316477
