Objective: Main clinical features of vascular parkinsonism (VP) are rigidity, fixed face, and short stepping gait. VP remains difficult to diagnose based on clinical features from patients with Parkinson’s disease (PD) without rest tremor. Olfactory dysfunction is a non-motor symptom in idiopathic PD. We investigated whether olfactory function can distinguish VP from PD. Method: Participants we...

Magnetic resonance imaging (MRI) allows to display brain structures with highest resolution. To fully exploit the potential of this imagining modality, data mining methods are required to reveal subtle differences in brain structure caused by disorders such as Mild Cognitive Impairment (MCI) and early stage Alzheimers disease (AD). In this paper, we propose a data mining framework which combine...

alzheimers disease (ad) is by far the most common cause of dementia. definite diagnosis of ad is based on pathological findings. nincds-adrda criteria, published more than 25 years ago, are commonly used for the clinical diagnosis of ad. however, considering serious shortcomings of these criteria, new criteria have been proposed. according to these new criteria, ad can be diagnosed in predement...

Acetyl-CoA provision to the synaptoplasmic compartment of cholinergic nerve terminals plays a regulatory role in the synthesis of acetylcholine. The disturbances in glucose utilization and in decarboxylation of the end product of its metabolism pyruvate, are considered to be significant factors causing cholinergic deficits in several diseases of the central nervous system. In this article we re...

background: sandhoff disease is an autosomal recessive disorder caused by β-hexosaminidase deficiency and accumulation of gm2 ganglioside resulting in progressive motor neuron manifestations and death from respiratory failure and infections in infantiles. pathogenic mutations in hexb gene were observed which leads to enzyme activity reduction and interruption of normal metabolic cycle of gm2 ga...
