We present a general model of why "thinking a lot" is a key presentation of distress in many cultures and examine how "thinking a lot" plays out in the Cambodian cultural context. We argue that the complaint of "thinking a lot" indicates the presence of a certain causal network of psychopathology that is found across cultures, but that this causal network is localized in profound ways. We show, using a Cambodian example, that examining "thinking a lot" in a cultural context is a key way of investigating the local bio-cultural ontology of psychopathology...

A 29-year-old man presented with scintillation scotoma. MR imaging demonstrated a diffuse lesion in right parahippocampal gyrus. He underwent a biopsy, and the diagnosis was diffuse astrocytoma. Because of enlargement and new areas of gadolinium enhancement, the tumor was resected 18 months after biopsy. Histological examination revealed malignant transformation to glioblastoma with small areas of epithelioid component. He received radiation and temozolomide chemotherapy. Local recurrence was found 20 months after first resection...

PURPOSE: To assess the character and cause of photopsias in vitreoretinal patients. DESIGN: Cross-sectional study. PARTICIPANTS: A total of 169 consecutive patients (217 eyes) with vitreoretinal disease presenting with a history of photopsias. METHODS: A total of 217 eyes with photopsias in 169 patients were evaluated. Photopsia assessment included (1) laterality (unilateral, bilateral but not simultaneous, bilateral, and simultaneous); (2) morphology (flash, zig-zag, strobe, scintillating scotoma, twinkling, other); (3) color (white, silver, yellow, combination, other); (4) location (temporal, central, other); (5) duration (quick, prolonged, constant, other); (6) frequency; (7) diurnal appearance (day, night, both); (8) stimuli (turning head or eyes, hypoglycemia, hyperglycemia, other); and (9) associated systemic or ocular signs and symptoms (headache, numbness, weakness, vertigo, syncope, diplopia, hypotension, floaters, other)...

Cortical spreading depolarization (SD) is a slow self-propagating wave of mass cellular depolarization in brain tissue, thought to be the underlying cause of migraine scintillating scotoma and aura, and associated with stroke, traumatic brain injury, and termination of status epilepticus. The N-methyl-d-aspartate subtype of glutamate receptor (NMDAR), which gates influx of calcium and is an important trigger of long-term synaptic plasticity, is also a contributor to the initiation and propagation of SD. The current study tested the potential of pharmacological modulation of NMDAR activity through the obligatory co-agonist binding site, to suppress the initiation of SD, and modulate the effects of SD on dendritic spine morphology, in in vitro hippocampal slices...

BACKGROUND: Cervical carotid dissection is more common in extracranical vessel: internal carotid artery dissection (ICAD) is typical, vertebral artery dissection is uncommon, common carotid artery dissection (CCAD) is rare and even a more rare cause of ischemic stroke. Cervical artery dissections account up to 20-25% of ischemic strokes in young patients. Isolated and spontaneous common carotid artery dissection without aortic damage is unique. Indeed in the Literature 8 cases were identified...

A migraine is a recurring neurological disorder characterized by unilateral, intense, and pulsatile headaches. In one-third of migraine patients, the attacks are preceded by a visual aura, such as a slowly-propagating scintillating scotoma. Migraine aura is thought to be a result of the neurovascular phenomenon of cortical spreading depression (SD), a self-propagating wave of depolarization that spreads across the cerebral cortex. Several animal experiments have demonstrated that cortical SD causes intracranial neurogenic inflammation around the meningeal blood vessels, such as plasma protein extravasation and pro-inflammatory peptide release...

BACKGROUND: Since the mid-19th century, epistaxis and migraine have been occasionally associated with each other. Nevertheless, we found only two cases in the contemporary medical literature. Sporadic hemiplegic migraine is a subtype of migraine with reversible motor deficits, without similar episodes in relatives. CASE: We describe a 47-year-old male with a history of migraine with a scintillating scotoma starting at the age of 20. In some of the episodes, he developed epistaxis in the resolution phase of migraine...

This article reports the case of a 14-year-old boy who was presented in the case conference with symptoms of decreased visual acuity, scintillating scotomas and photophobia. Physical examination revealed right facial paralysis, parotid gland swelling, high fever and poor general condition. Ophthalmoscopy revealed anterior and posterior uveitis including macular edema and chorioretinal infiltrates. Angiography revealed a dense pattern of hyperfluorescent lesions and these observations resulted in the diagnosis of Heerfordt syndrome...

We report a very unusual case of a composite high-grade glioma and rhabdoid tumor in an adult. A 22-year-old woman presented with scintillating scotoma due to a solid tumor with surrounding brain edema in the right occipital lobe. The tumor was grossly resected. Histological examinations showed that the tumor was mainly composed of INI1-positive high-grade glioma tissue containing an INI1-negative rhabdoid component. She received radiation therapy and chemotherapy. Three months after the surgery, she again complained of visual disturbances, and tumor recurrence within the resection cavity was noted...

Until the second half of the eighteenth century, the very definition of migraine as hemicrania (pain felt in one side of the head) eclipsed symptoms that were then considered as "marginal", although tingling sensations, speech impairment and visual impairment had already been described by Piso and Wepfer. The possibility of a migraine without a headache nevertheless started to be envisaged, inviting one to re-evaluate the status of these phenomena. But, as paradoxical as it may seem, it is in the field of astronomy that some of these phenomena such as visual aberrations were analyzed systematically and acknowledged to be migrainous...

We compared the appearance of a line passing through the optic-disc blind spot with that of lines passing just medial or just lateral to the blind spot. Though there is no well-defined gap in the line, we see a consistent difference, which is hard to describe. On the other hand, during a migraine aura experienced by one of us, lines passing through scintillating scotomas showed clear sharply defined gaps.

BACKGROUND: Polyglycolic-polylactic acid (PGLA) coils induce inflammation within a cerebral aneurysm, which in turn is hypothesized to decrease aneurysm recurrence. We present 2 patients, who after aneurysm coiling with PGLA coils, developed mild symptoms and extensive magnetic resonance imaging (MRI) white matter changes. METHODS: The first patient was a 46-year-old woman who underwent coiling of a 6.8 × 6.8 × 7.0-mm incidentally discovered basilar apex aneurysm...

DEFINITION: Sclerotherapy is defined as the targeted elimination of small vessels, varicose veins and vascular anomalies by the injection of a sclerosant. The aim of sclerotherapy is to damage the vessel wall and transform it into a fibrous cord that cannot be recanalized. It is a simple, cost-effective, efficacious and esthetically acceptable modality for both therapeutic and esthetic purposes. INDICATIONS: Therapeutic indications include varicose veins and vascular malformations...

REVIEW
Pari N Shams, Gordon T Plant
Visual aura is a common presenting symptom of migraine to both neurologists and ophthalmologists. Features such as photopsia, fortification spectra, and the slow propagation of a scintillating scotoma across the visual field are usually considered diagnostic features of the visual aura of migraine. In the vast majority of cases, the diagnosis can be made without the need for further investigations. We present 9 patients and a further 31 cases from the literature who experienced visual aura fulfilling the diagnostic criteria for migraines but caused by focal occipital pathology...

The intracarotid sodium amobarbital (Amytal) test, the Wada test, remains an efficient test for evaluation of language and memory function. However, due to a world shortage of amobarbital, it has become necessary to investigate the use of alternatives. We report the efficacy of the Wada test using secobarbital sodium (Ional) in determining language dominance. An accurate determination of language dominance was required in 43 patients preoperatively at our institution. Patients underwent the Wada test using secobarbital sodium, effectiveness and safety were assessed...

INTRODUCTION: Migraine with aura is characterized by reversible focal neurological symptoms preceding or accompanying headache. Visual aura is the most common type of aura and its patognomic symptoms are scintillating fortification migrating across the visual field or scintillating scotoma. However, the symptoms are not always so typical and clinical doubts are greater when negative symptoms (loss of vision, numbness or paresis) are present. Differential diagnosis of migraine with aura includes in the first place transient ischemic attack (TIA) as well as epilepsy...

BACKGROUND: Transseptal catheterization (TSC) is performed during catheter ablation involving the lefthand side of the heart. TSC causes a transient iatrogenic atrial septal defect that can predispose patients to migraine episodes. However, isolated migraine aura episodes in patients undergoing TSC have not been described. METHODS: Five hundred seventy-one procedures involving TSC were performed over a 3-year duration. Of these, 3 patients presented with visual symptoms in the first month after the procedure...
