Comparison of elderly and young patient populations treated with deep brain stimulation for Parkinson's disease: long-term outcomes with up to 7 years of follow-up.

Objective: Deep brain stimulation (DBS) is the procedure of choice for Parkinson's disease (PD). It has been used in PD patients younger than 70 years because of better perceived intra- and postoperative outcomes than in patients 70 years or older. However, previous studies with limited follow-up have demonstrated benefits associated with the treatment of elderly patients.

Effect of creatine monohydrate on clinical progression in patients with Parkinson disease: a randomized clinical trial.

Importance: There are no treatments available to slow or prevent the progression of Parkinson disease, despite its global prevalence and significant health care burden. The National Institute of Neurological Disorders and Stroke Exploratory Trials in Parkinson Disease program was established to promote discovery of potential therapies.

Objective: To determine whether creatine monohydrate was more effective than placebo in slowing long-term clinical decline in participants with Parkinson disease.

Periodic eyelid opening associated with burst-suppression electroencephalography due to hypoxic ischemic injury.

Background: We report four patients who developed periodic eyelid opening following hypoxic ischemic injury. This manuscript reviews the clinical course of our patients as well as previously published cases and discusses the neuroanatomical basis of eyelid opening.

Methods: Data were collected from the patients' electronic medical record and digital electroencephalography recordings.

Brain-lung-thyroid disease: clinical features of a kindred with a novel thyroid transcription factor 1 mutation.

Brain-lung-thyroid disease is a rare familial disorder caused by mutations in thyroid transcription factor 1, a gene that regulates neuronal migration. We report the clinical features of ten patients from a single family with a novel gene mutation, including observations regarding treatment. Neurologic features of the kindred included developmental delay, learning difficulties, psychosis, chorea, and dystonia.

Cognitive and neuropsychiatric effects of subthalamotomy for Parkinson's disease.

Since the advent of deep brain stimulation (DBS) for the treatment of Parkinson's disease (PD), subsequent cognitive and neuropsychiatric effects of this procedure have become well-chronicled. Yet, thermolitic lesion of the subthalamic nucleus (STN) is still a valid option when DBS cannot be applied, and little has been published regarding its impact on cognition and mood. We examined the cognitive and neuropsychiatric functions of 10 consecutive patients with advanced PD undergoing simultaneous bilateral subthalamotomies.

Rapidly progressive atypical parkinsonism associated with frontotemporal lobar degeneration and motor neuron disease.

Objective: To report the rare but distinct clinical and neuropathological phenotype of non-familial, rapidly progressive parkinsonism and dementia associated with frontotemporal lobar degeneration with motor neuron disease (FTLD-MND).

Methods: Subjects included two 70-year-old women presenting with rapidly progressive severe postural instability, axial-predominant parkinsonism, oculomotor dysfunction and frontal-predominant dementia with language impairment and pseudobulbar palsy. One had diffuse weakness without signs of lower motor neuron disease.

Unraveling progressive supranuclear palsy: from the bedside back to the bench.

Progressive supranuclear palsy (PSP) typically presents with a gradual onset and progressive course of symmetric levodopa-unresponsive parkinsonism characterized by postural instability with falls, supranuclear vertical gaze palsy, dysarthria, dysphagia, and cognitive and behavioral disturbances. Though the clinical course is variable, the typical presentation is usually associated with mortality at 5-9 years after symptom onset. The pathological hallmark of PSP is widespread neuronal cell loss with deposition of aggregated hyperphosphorylated tau, particularly within the midbrain.

Palliative care in amyotrophic lateral sclerosis, Parkinson's disease, and multiple sclerosis.

Background: Amyotrophic lateral sclerosis, Parkinson's disease, atypical parkinsonian syndromes, and multiple sclerosis are progressive neurologic disorders that cumulatively afflict a large number of people. Effective end-of-life palliative care depends upon an understanding of the clinical aspects of each of these disorders.

Objectives: The authors review the unique and overlapping aspects of each of these disorders with an emphasis upon the clinical management of symptoms.

Treatment-responsive limbic encephalitis identified by neuropil antibodies: MRI and PET correlates.

We report seven patients, six from a single institution, who developed subacute limbic encephalitis initially considered of uncertain aetiology. Four patients presented with symptoms of hippocampal dysfunction (i.e.
