Background: Parkinsonism like features can be seen in cirrhotics, possibly related to alterations in brain dopamine metabolism, transport and receptor integrity at basal ganglia. Hepatic parkinsonism [HP] is often not suspected and only ammonia reducing therapies are given to such patients. We investigated the efficacy and safety of bromocriptine, a dopaminergic agent, in patients with HP. Read More

Alzheimer's disease (AD) is characterized by the accumulation of amyloid-β peptide (Aβ) and hyperphosphorylated Tau protein (P-Tau). Our recent data showed a differential accumulation of Tau protein phosphorylated at Thr231 in distinct hippocampal neurons in VLW mice-an animal model that overexpresses mutated human Tau. Here we demonstrate that, in VLW mice, the accumulation of human P-Tau in the pyramidal cells induces the phosphorylation of murine Tau at Thr231 (pThr231) in hippocampal interneurons. Read More

Introduction: It remains to be clarified whether penetration of the caudate nucleus increases the risk of cognitive decline in patients with Parkinson's disease (PD) undergoing deep brain stimulation (DBS) of the subthalamic nucleus (STN).
Methods: A retrospective analysis of pre/postoperative neuropsychological changes was performed with 46 consecutive patients with PD who underwent DBS of the STN. In particular, to evaluate the possible relationship between cognitive changes and DBS lead trajectories, repeated-measures ANCOVAs were conducted to analyze the effects of group (23 patients with vs 23 patients without penetration of the caudate nucleus) and time (T0 vs T1) for each neuropsychological test.

Synchronized oscillations within and between brain areas facilitate normal processing, but are often amplified in disease. A prominent example is the abnormally sustained beta-frequency (∼20Hz) oscillations recorded from the cortex and subthalamic nucleus of Parkinson's disease patients. Computational modelling suggests that the amplitude of such oscillations could be modulated by applying stimulation at a specific phase. Read More

The non-proteinogenic amino acid beta-methyl-amino-l-alanine (BMAA) is a neurotoxin produced by cyanobacteria. BMAA accumulation in the brain of animals via biomagnification along the food web can contribute to the development of neurodegenerative diseases such as Amyotrophic lateral sclerosis/Parkinsonism dementia complex (ALS/PDC), the latter being associated with a loss of dopaminergic neurons. is an important microcrustacean zooplankton species that plays a key role in aquatic food webs, and BMAA-producing cyanobacteria often form part of their diet.

Preclinical and clinical evidences have demonstrated that astroglial-derived S100B protein is a key element in neuroinflammation underlying the pathogenesis of Parkinson's disease (PD), so much as that S100B inhibitors have been proposed as promising candidates for PD targeted therapy. Pentamidine, an old-developed antiprotozoal drug, currently used for pneumocystis carinii is one of the most potent inhibitors of S100B activity, but despite this effect, is limited by its low capability to cross blood brain barrier (BBB). To overcome this problem, we developed a non-invasive intranasal delivery system, chitosan coated niosomes with entrapped pentamidine (inPentasomes), in the attempt to provide a novel pharmacological approach to ameliorate parkinsonism induced by subchronic MPTP administration in C57BL-6 J mice.

Parkinson's disease (PD) is caused by a progressive degeneration of nigral dopaminergic cells leading to striatal dopamine deficiency. From the perspective of antiparkinsonian drug mechanisms, pharmacologic treatment of PD can be divided into symptomatic and disease-modifying (neuroprotective) therapies.

This study is aimed to determine whether enumeration of brain-derived exosomes (BDEs) in plasma is informative in the diagnosis of those diseases.
Methods: We have developed a specific method to enumerate the plasma levels of neuron-derived, astrocyte-derived, and oligodendrocyte-derived exosomes (NDEs, ADEs and ODEs, respectively), and quantified them individually in patients with PD (n = 15), multiple system atrophy (MSA, n = 15), progressive supranuclear palsy (PSP, n = 7) and disease controls (n = 15).

The proper diagnosis of parkinsonian disorders usually involves three steps: identifying core features of parkinsonism; excluding other causes; and collating supportive evidence based on clinical signs or investigations. While the recognition of cardinal parkinsonian features is usually straightforward, the appreciation of clinical features suggestive of specific parkinsonian disorders can be challenging, and often requires greater experience and skills. In this review, we outline the clinical features that are relevant to the differential diagnosis of common neurodegenerative parkinsonian disorders, including Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration.

Background: In old age, motor impairments including parkinsonian signs are common, but treatment is lacking for many older adults. In this study, we examined the association of a diet specifically developed to promote brain health, called MIND (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay), to the incidence and progression of parkinsonism in older adults.
Methods: A total of 706 Memory and Aging Project participants aged 59 -97 years and without parkinsonism at baseline were assessed annually for the presence of four parkinsonian signs using a 26-item modified version of the United Parkinson's Disease Rating Scale. Read More

OBJECTIVEFor patients with highly asymmetrical Parkinson's disease (PD), unilateral subthalamic nucleus (STN) deep brain stimulation (DBS) has been suggested as a reasonable treatment. However, the results of a previous 2-year follow-up study involving patients with prominently asymmetrical PD who had unilateral STN DBS suggested that simultaneous bilateral surgery should be performed. In the present study, the authors analyze 7-year follow-up data from the same patient group to examine changes in motor benefit from unilateral STN DBS over time and the interval between initial unilateral surgery and a second (contralateral) STN DBS surgery.
