Alzheimer's disease clinical and research update for health care practitioners.

Of the approximately 6.8 million Americans who have been diagnosed with dementia, over 5 million have been diagnosed with Alzheimer's Disease (AD). Due to the rise in the aging population, these figures are expected to double by 2050.

PRISM: a novel research tool to assess the prevalence of pseudobulbar affect symptoms across neurological conditions.

Background: Pseudobulbar affect (PBA) is a neurological condition characterized by involuntary, sudden, and frequent episodes of laughing and/or crying, which can be socially disabling. Although PBA occurs secondary to many neurological conditions, with an estimated United States (US) prevalence of up to 2 million persons, it is thought to be under-recognized and undertreated. The PBA Registry Series (PRISM) was established to provide additional PBA symptom prevalence data in a large, representative US sample of patients with neurological conditions known to be associated with PBA.

Improving outcomes of severe disorders of consciousness.

Purpose: To evaluate the efficacy of an Advanced Care Protocol (ACP) in improving rates of clinical progression and emergence in patients with Severe Disorders of Consciousness (SDOC).

Methods: Forty-one patients with SDOC were assigned to groups: Vegetative State (VS) traumatic etiology (VS-TBI), VS non-traumatic etiology (VS-NTBI), Minimally Conscious State (MCS-TBI), MCS non-traumatic etiology (MCS-NTBI). Design was a within-subjects retrospective case series measuring pre-post ACP intervention data.

The new neuroscience frontier: promoting neuroplasticity and brain repair in traumatic brain injury.

Increased awareness of traumatic brain injury (TBI) in the military, a persistent call for evidence-based treatment, and recent government funding have revealed new research opportunities in neuroscience. This paper describes a relatively new frontier for research: that of the facilitation or enhancement of neuroplasticity and brain repair in TBI using novel treatment protocols. Such protocols, algorithmically introduced, may be tailored to the individual through the matching of neuromarkers with specific interventions.

False localizing signs in traumatic brain injury.

Background: Hemiparesis ipsilateral to a mass-occupying lesion can be due to Kernohan-Woltman Notch Phenomenon (KWNP). This syndrome implies a false-localizing sign because clinical findings lead the examiner to an incorrect neuroanatomical diagnosis. The contralateral crus cerebri (pyramidal tract) is pressed against the tentorial incisum and a resultant hemiparesis is found on the same side of the lesion.
