Epileptic phenomena are usually not considered a possible cause of prolonged hallucinatory states such as Charles Bonnet syndrome (CBS). A 65-year-old woman with previous right hemorrhagic strokes developed complex visual hallucinations (CVHs), featuring CBS, and delayed palinopsic phenomena, along
The Charles Bonnet syndrome (CBS) commonly designates visual hallucinations (VH) occurring in visually impaired patients. However, there is no consensual definition. The existence of an ophthalmic disease and the absence of cognitive impairment are mandatory or not according to the proposed
The rationale and technique of the bonnet bypass procedure is discussed in two cases of multiple cerebrovascular occlusive disease.
METHODS
Cerebral revascularization was achieved using respectively a radial artery interposition graft and a brachiocephalic vein interposition graft to connect the
A 30-year-old man presented with new onset severe headache and homonymous hemianopia, with a subsequent seizure, on a background of a right parietal astrocytoma resected at age 5 with adjuvant chemotherapy and radiotherapy. Magnetic resonance imaging of the brain revealed post-surgical and
The congenital retinocephalic facial vascular malformation syndrome is characterized by unilateral, nonhereditary retinal and cerebral arteriovenous malformations (AVMs) and is occasionally associated with orbital vascular changes. Typical signs are facial and oral mucosal vascular changes, rarely
The superficial temporal artery (STA) to the middle cerebral artery (MCA) bypass is the most common bypass type for revascularization to treat cerebral ischemia. If the ipsilateral STA is not available for anastomosis, various options for bypass conduits can be exercised. When the entire ipsilateral
BACKGROUND
In reverse bypass that used a naturally formed "bonnet" superficial temporal artery, intraoperative volume flow measurement quantifies flow augmentation after revascularization, confirms flow preservation, and identifies inadvertent vessel compromise.
METHODS
A 75-year-old man presented
BACKGROUND
Charles Bonnet syndrome (CBS) is an uncommon disorder characterized by complex and recurrent visual hallucinations in patients with visual pathway pathologic defects.
OBJECTIVE
To describe a patient who experienced complex visual hallucinations following infarction in the right occipital
We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient
Wrapping low-birth-weight neonates in a plastic bag prevents body heat loss. A bonnet can also be used, since large amounts of heat can be lost from the head region, but may provide too much thermal insulation, thus increasing the risk of overheating. We assessed the time required to reach warning
Vivid visual hallucinations are common in the geriatric population and can be due to a number of causes such as dementia, delirium, stroke, adverse effects of medication, or ocular disease. We will examine an interesting patient case report, which allowed us to explore two lesser-known causes of
UNASSIGNED
Early life stress (ELS) in macaques in the form of insecure maternal attachment putatively induces epigenetic adaptations resulting in a "thrifty phenotype" throughout the life cycle. For instance, ELS induces persistent increases in insulin resistance, hippocampal and corpus callosum
OBJECTIVE
Visual hallucinations can occur within the central nervous system and may be associated with a lesion anywhere in the visual pathway. The purpose of this study was to assess "ictal" regional cerebral blood flow with Tc-99m ethylcysteinate dimer (ECD) SPECT in patients having acute
