Article Synopsis
- - This study investigates how transcranial Doppler ultrasound (TCD) can detect changes in blood flow that might indicate vasculitis in patients with neurocysticercosis (NCC), a condition that can lead to strokes.
- - Out of 53 NCC patients, 12 (22.64%) showed hemodynamic changes linked to vasculitis, primarily affecting the middle cerebral artery, with a higher occurrence in females.
- - The findings suggest that TCD is a valuable tool for identifying cerebral hemodynamic changes in NCC patients, highlighting the importance of monitoring for complications like vasculitis.
Objectives: Evaluate clinical outcomes of stroke survivors in Peru discharged with artificial nutrition via a feeding tube (FT), and explore perspectives and experiences of these patients and their caregivers.
Methods: Retrospective chart review to describe the prevalence of FT placement and characteristics of patients admitted with stroke to the Instituto Nacional de Ciencias Neurológicas in Lima, Peru between January 2019 and 2021. Follow-up calls to stroke survivors discharged home with FTs or their caregivers included quantitative and qualitative questions to assess long-term outcome and explore perspectives around poststroke care and FT management.
Carotid web (CW) is considered a variant of intimal fibromuscular dysplasia. CW represents between 9.4% and 37% of ischemic strokes that were initially misclassified as "cryptogenic.

Clinically, MMD can present with ischemic or hemorrhagic cerebrovascular events. The term Moyamoya syndrome (MMS) is used when the characteristic Moyamoya vasculopathy presents in association with other conditions such as Graves' disease (GD).

- Spinal dural arteriovenous fistula (SDAVF) is an abnormal connection between a blood vessel and a vein in the spine, leading to issues like spinal cord venous congestion and a variety of nonspecific sensory and motor symptoms.
- The document highlights three cases of SDAVF that presented differently; two cases were initially thought to be autoimmune conditions, while the third was misdiagnosed as chronic radiculopathy.
- All cases displayed distinct imaging features that helped confirm SDAVF, emphasizing the need to consider it in unusual presentations of radiculopathy or related spinal disorders, especially in comparison to demyelinating diseases.
Article Synopsis
- Reversible cerebral vasoconstriction syndrome (RCVS) often causes convexal subarachnoid hemorrhage and is marked by sudden, severe headaches known as thunderclap headaches, along with specific patterns of intracranial blood vessel narrowing.
- The condition can lead to serious complications, like intracerebral hemorrhage, seizures, and ischemic stroke.
- The case study discusses a 51-year-old woman diagnosed with RCVS who initially showed normal digital subtraction angiography, emphasizing the significance of recognizing thunderclap headaches and the need for follow-up angiographic studies if RCVS is suspected.
Carotid web (CW) is an atypical form of intimal fibromuscular dysplasia that occurs at the level of the carotid bulb. It is associated with ischemic strokes. The first report of this association was in 1967 and it is currently known to represent a significant percentage of cryptogenic stroke.

Rev Peru Med Exp Salud Publica
April 2014
Creutzfeldt-Jakob disease (CJD) is a fatal neurological disease caused by pathological isoform of the human prion protein. Clinical features of six cases of the sporadic form of CJD with definitive diagnosis by histopathology, and five cases with probable diagnosis were reported in patients treated at the Peruvian National Institute of Neurological Sciences. The average age of onset in definite cases was 55.

- Chorea is a rare movement disorder that can occasionally occur due to erythrocytosis, a condition characterized by an increase in red blood cell mass.
- Primary erythrocytosis is often caused by polycythemia vera, while secondary causes can include living at high altitudes, leading to reduced oxygen levels.
- A case study reported a 71-year-old man experiencing sudden generalized chorea predominantly affecting his mouth, tongue, face, and lower limbs, which improved after treatment to lower his red blood cell count through phlebotomy.
