Neuropsychiatric disorders caused by cobalamin deficiency in the absence of anemia or macrocytosis.
TLDR
It is concluded that neuropsychiatric disorders due to cobalamin deficiency occur commonly in the absence of anemia or an elevated mean cell volume and that measurements of serum methylmalonic acid and total homocysteine both before and after treatment are useful in the diagnosis of these patients.
Neurologic Aspects of Cobalamin Deficiency
TLDR
A wide variety of neurologic symptoms and signs were encountered, however, including ataxia, loss of cutaneous sensation, muscle weakness, diminished or hyperactive reflexes, spasticity, urinary or fecal incontinence, orthostatic hypotension, Loss of vision, dementia, psychoses, and disturbances of mood.
CXCR4 and CXCL12 Expression is Increased in the Nigro-Striatal System of Parkinson’s Disease
TLDR
The results suggest that CXCL12/CXCR4 may participate in the etiology of PD and indicate a new possible target molecule for PD.
Pseudotumor cerebri, empty sella syndrome, and adrenal adenoma
TLDR
Questions are raised about the treatment of BIH with corticosteroids, which are of unproved efficacy and may sometimes cause the same clinical syndrome.
Hypertensive encephalopathy and the neurologic manifestations of malignant hypertension
TLDR
Patients with 41 admissions for malignant hypertension were examined by a neurologist before and after antihypertensive treatment, and five patients had a generalized neurologic syndrome consistent with hypertensive encephalopathy, characterized by altered mental function with or without generalized convulsions.
Intracranial subdural sarcoid granuloma. Case report.
TLDR
Neither symptoms nor nonhistological diagnostic studies, including computerized tomography, differentiate sarcoid from cerebral neoplasms or other central nervous granulomas, and surgery should probably be reserved for cases in which there is diagnostic uncertainty, a need for emergency decompression, or lack of response to steroids.
Language disorder in a right‐hander after occlusion of the right anterior cerebral artery
TLDR
A right-handed woman developed left hemiparesis and a language disturbance and represents the fourth autopsy case of “crossed aphasia in a dextral” and the first, with or without autopsy, after right anterior cerebral artery occlusion.
Presumably Azorean disease in a presumably non‐Portuguese family
TLDR
The family reported here may be the first example of ADMSD in a non-Portuguese family and four members of a family had cerebellar ataxia, dystonic posturing, a variety of abnormal eye movements, and prominent eyes resulting from lid retraction.
Nonspecificity of ring enhancement in “medically cured” brain abscess
TLDR
Clinical experience and experimental work indicate that the “ring sign” on contrast-enhanced CT is not absolutely diagnostic of encapsulated brain abscess, and atypical clinical features suggest that some patients may have had cerebral infarction or cerebritis.
