Secondary parkinsonism has comprised about 20 to 40 percent of all parkinsonism patients in movement disorders clinic. Most of them are induced by certain medications. About 5 to 10 percent of these patients are caused by sudden vascular events, who suffer from their parkinsonism abruptly, and usually of aged people with quite apparent stroke risk factors. Hemosiderosis was only occasionally reported as a causative factor in patients with parkinsonism, who presented with an insidious onset…

Vascular parkinsonism

Functional imaging of presynaptic dopamine transporter may be useful in the differentiation of VP from PD, and major risk factors for VP are principally the same as those for cerebrovascular disease, and their prevention and treatment are of utmost importance.

Rheumatoid Meningitis Mimicking Progressive Supranuclear Palsy

A 71-year-old woman with 15 years of seropositive rheumatoid arthritis who developed neurological complications: cognitive deterioration; hypomimia; limitation on vertical gaze; and axial stiffness, resembling progressive supranuclear palsy and seizures is reported.

Spontaneous spinal epidural haematomas in children

SSEHs affect all paediatric age groups and typically present with neurological dysfunction and/or back pain, and the initial diagnosis is incorrect in up to 28% of cases, but cross-sectional spinal imaging is diagnostic.

Neurosurgery Spontaneous Spinal Epidural Haematomas in Adults: A Systematic Review

SSEH affects all age groups and presents with variable neurological signs sometimes mimicking or ischaemia, and most patients will improve or resolve their neurological deficit with appropriate management.

Spontaneous Spinal Epidural Haematomas in Adults: A Systematic Review

SSEH affects all age groups and presents with variable neurological signs sometimes mimicking cerebral or cardiac ischaemia, but with appropriate management most patients will improve or resolve their neurological deficit.

Spontaneous spinal epidural haematomas

The authors stress the importance of correct and fast decisions at the first medical examination for the outcome of this disease, because only immediate transfer to a neurosurgical department gives a chance of good recovery.

Spontaneous Spinal Epidural Haematomas

This chapter reviews the presentation, diagnosis and treatment of SSEH in adults, pregnancy and children in order to provide clinicians with an understanding of their typical presentation, required investigations and treatment algorithms.



Vascular parkinsonism

This review tentatively delineates the extent of the spectrum of VP, which refers to isolated gait disorders called “lower body parkinsonism”, “frontal-type gait Disorders” or “gait ignition failure” that are reminiscent of, but distinct from, that found in IPD.

Clinical correlates of vascular parkinsonism.

Compared with PD, patients with parkinsonism associated with vascular disease are more likely to present with gait difficulty and postural instability rather than tremor, have a history of stroke and risk factors for stroke, and fail to respond to levodopa therapy.

The basal ganglia in haemochromatosis

Investigation of patients with hereditary haemochromatosis with MRI, CT and transcranial ultrasound found dense lesions were found within the lentiform nucleus on CT, all of whom displayed hyperechogenic lesions in the same area on TCS, as did one other patient.

Magnetic resonance imaging of cerebral microbleeds.

Correlative histopathologic data have recently confirmed a strong association between the occurrence of microbleeds and various types of small vessel disease, such as hypertensive lipofibrohyalinosis and cerebral amyloid angiopathy, and microbleed that are detectable by magnetic resonance imaging could be viewed as markers for vessel wall disorders with a higher tendency for intracerebral bleeding.

MRI evidence of past cerebral microbleeds in a healthy elderly population

MRI evidence of past microbleeds may be found even in neurologically normal elderly individuals and is related, but not restricted, to other indicators of small vessel disease.

A new cause of hereditary small vessel disease

A family in which six members from three successive generations developed a diffuse leukoencephalopathy with familial variants of cerebral amyloid angiopathy is reported.

Vascular Parkinsonism

The article reviews the recent development in the changes of vascular Parkinsonism in epidemiology, etiology, pathology, biochemistry, electrophysiology imaging, as well as the clinical presentation and diagnosis.

Primary angiitis of the central nervous system and silent cortical hemorrhages.

The identification of petechial hemorrhages by gradient-echo MR imaging promises to be a valuable surrogate marker supporting the diagnosis of primary angiitis of the CNS.

Hereditary ceruloplasmin deficiency with hemosiderosis

Hereditary ceruloplasmin deficiency with hemosiderosis (aceruloplasminemia) is a new disease characterized by systemic hemosiderosis, diabetes mellitus, neurological abnormalities and pigment

Cerebral Microbleeds as a Risk Factor for Subsequent Intracerebral Hemorrhages Among Patients With Acute Ischemic Stroke

Cerebral microbleeds appear to be a risk factor for subsequent intracerebral hemorrhage among patients with ischemic stroke in this small cohort of Chinese stroke patients.
