<bibitem lang="en">  The anti-influenza virus drug oseltamivir has been reported to have several pharmacological actions including blocking of nicotinic acetylcholine receptor channels and activation of the dopaminergic system. These pharmacological actions highly overlap those of amantadine, another anti-influenza virus drug authorized in Japan, and ester-type local anesthetics. Moreover, oseltamivir and amantadine can clinically induce similar adverse neuropsychiatric reactions. In the present study, from the database of the Pharmaceuticals and Medical Devices Agency (PMDA), we surveyed 2,576 drugs for which neuropsychiatric side effects similar to those of oseltamivir, amantadine and local anesthetics (abnormal behavior, confusion, consciousness disturbance, convulsion, delirium, delusion, hallucination, myoclonus, tremor) are listed as "clinically significant adverse reactions", and found 327 that had at least one of these adverse reactions...

INTRODUCTION: Amantadine, as a dopamine receptor agonist, may stimulate and help the recovery of the nervous system after traumatic brain injury (TBI). METHODS: We performed this study as a double-blind, randomized, controlled clinical trial with target population including all patients with TBI who scored nine or lower on the Glasgow Coma Scale (GCS), admitted to our hospital between January 2013 and April 2014. The protocol included administration of the drug (placebo or amantadine) for 6 weeks and patient evaluation using the GCS and FOUR score on the first, third and seventh days after the drug was started...

PURPOSE OF REVIEW: Very few options exist for patients who survive severe traumatic brain injury but fail to fully recover and develop a disorder of consciousness (e.g. vegetative state, minimally conscious state). RECENT FINDINGS: Among pharmacological approaches, Amantadine has shown the ability to accelerate functional recovery. Although with very low frequency, Zolpidem has shown the ability to improve the level of consciousness transiently and, possibly, also in a sustained fashion...

PURPOSE OF REVIEW: This article evaluates whether specific drugs are able to facilitate motor recovery after stroke or improve the level of consciousness, cognitive, or behavioral symptoms after traumatic brain injury. RECENT FINDINGS: After stroke, serotonin reuptake inhibitors can enhance restitution of motor functions in depressed as well as in nondepressed patients. Erythropoietin and progesterone administered within hours after moderate to severe traumatic brain injury failed to improve the outcome...

A 78-year-old woman was transferred to our hospital for clouded consciousness and a high fever. She had been diagnosed with Parkinsonian syndrome, which was controlled with amantadine. Hallucination appeared a week prior to the transfer and she was treated with haloperidol. Suspecting neuroleptic malignant syndrome, dantrolene sodium was administered along with symptomatic treatment with mechanical ventilation and cooling. Her symptoms were reversed and she was transferred to another hospital for neurological evaluation...

Electroencephalography (EEG) often fails to assess both the level (i.e., arousal) and the content (i.e., awareness) of pathologically altered consciousness in patients without motor responsiveness. This might be related to a decline of awareness, to episodes of low arousal and disturbed sleep patterns, and/or to distorting and attenuating effects of the skull and intermediate tissue on the recorded brain signals. Novel approaches are required to overcome these limitations. We introduced epidural electrocorticography (ECoG) for monitoring of cortical physiology in a late-stage amytrophic lateral sclerosis patient in completely locked-in state (CLIS)...

Amantadine hydrochloride is one of the most commonly used drugs in the pharmacotherapeutic treatment of disorders of consciousness (DOCs) following traumatic brain injury (TBI). Indeed, its actions as a pro-dopaminergic drug and as an N-methyl-D-aspartate antagonist makes amantadine an interesting candidate to improve consciousness and responsiveness in individuals with DOC, including vegetative state and minimally conscious state. Giacino et al (N Engl J Med. 2012;366(9):819-826) recently reported that amantadine was able to accelerate the functional recovery course of subjects after TBI with DOC, during a 4-week treatment period...

Survivors of severe brain injuries may end up in a state of 'wakeful unresponsiveness' or in a minimally conscious state. Pharmacological treatments of patients with disorders of consciousness aim to improve arousal levels and recovery of consciousness. We here provide a systematic overview of the therapeutic effects of amantadine, apomorphine and zolpidem in patients recovering from coma. Evidence from clinical trials using these commonly prescribed pharmacological agents suggests positive changes of the patients' neurological status, leading sometimes to dramatic improvements...

Oxygen based neurotransmitters in the synapses of the brain are proposed to play an important role in the generation of consciousness. They include the amino acids glutamate and GABA which use Krebs cycle precursors for their synthesis, and the monoamines dopamine, noradrenalin, adrenalin and serotonin, which are derived from tyrosine and tryptophan. During ischemia after an acute brain injury, a GABA surge often initiates brain suppression. It has been proposed that with chronic ischemia, a secondary, possibly epigenetic response occurs when neurotransmitters deplete, a glucose and oxygen saving mechanism termed neurodormancy that may invoke alternative long term low energy metabolic pathways in the brain, encountered in Disorders of Consciousness...

The neurobiological approach to consciousness moves from the assumption that all phenomenal experiences are based on neuronal activity in the brain. Consciousness has two main components: wakefulness and awareness. While it may be relatively easy to determine the neuronal correlates of wakefulness, it is not the same for awareness, of which the neural correlates are poorly understood. Knowledge of the circuitry and the neurochemistry of the sleep/wake condition is necessary but not sufficient to understand the circuitry and neurochemistry of consciousness...

Despite the development of strong antibiotics, the pneumonia death is increasing all over the world in these decades. Among the people who died of pneumonia, the majority were 65 years old or over. Although pneumonia is recently categorized into several entities, aspiration pneumonia includes all entities. Therefore, targeting dysphagia and aspiration to treat pneumonia is a promising strategy and anti-aspiration drugs will be a part of pneumonia treatment. The swallowing reflex in elderly people was temperature-sensitive and the improvement of swallowing reflex by temperature stimuli could be mediated by the thermosensing TRP channels at pharynx...

OBJECTIVE: To assess the incidence of medical complications in patients with recent traumatic disorders of consciousness (DOCs). DESIGN: Data on adverse events in a placebo controlled trial of amantadine hydrochloride revealed no group difference, which allowed these events to be reanalyzed descriptively as medical complications experienced by the 2 groups collectively. SETTING: Eleven clinical facilities in the United States, Denmark, and Germany with specialty rehabilitation programs for patients with DOCs...

BACKGROUND: Amantadine hydrochloride is one of the most commonly prescribed medications for patients with prolonged disorders of consciousness after traumatic brain injury. Preliminary studies have suggested that amantadine may promote functional recovery. METHODS: We enrolled 184 patients who were in a vegetative or minimally conscious state 4 to 16 weeks after traumatic brain injury and who were receiving inpatient rehabilitation. Patients were randomly assigned to receive amantadine or placebo for 4 weeks and were followed for 2 weeks after the treatment was discontinued...

Disorders of consciousness (DOC) include coma, vegetative state (VS) and minimally conscious state (MCS). Coma is a condition of unarousability with a complete absence of wakefulness and awareness, whereas VS is characterized by a lack of awareness despite a preserved wakefulness. Patients in coma are unconscious because they lack both wakefulness and awareness. Patients in a VS are unconscious because, although they are wakeful, they lack awareness. Patients in a MCS show minimal but definite behavioural evidence of self and environmental awareness...
