The efficacy and safety of pharmacological treatments for post-stroke aphasia.
Conclusions Current evidence suggests that drugs can improve the prognosis of post-stroke aphasia, such as donepezil, memantine. Donepezil has a significant effect in improving the ability of auditory comprehension, naming, repetition and oral expression. Memantine has a significant effect in improving the ability of naming, spontaneous speech and repetition. Bromocriptine showed no significant improvement in the treatment of aphasia after stroke. The trial for galantamine, amphetamine and levodopa in the treatment of aphasia after stroke is limited and inconclusive. PMID: 29984673 [PubMed - as supplied by publisher]

Modafinil for the Improvement of Patient Outcomes Following Traumatic Brain Injury
Conclusion. Modafinil is a central nervous system stimulant with well-established effectiveness in the treatment of narcolepsy and shift-work sleep disorder. There is conflicting evidence about the benefits of modafinil in the treatment of fatigue and EDS secondary to TBI. One randomized, controlled study states that modafinil does not significantly improve patient wakefulness, while another concludes that modafinil corrects EDS but not fatigue. An observational study provides evidence that modafinil increases alertness in fatigued patients with past medical history of brainstem diencephalic stroke or multiple sclerosis. ...

Pharmacotherapy and motor recovery after stroke.
Authors: Viale L, Catoira NP, Di Girolamo G, González CD Abstract INTRODUCTION: Stroke is one of the most prevalent neurological diseases worldwide, especially among the elderly population. There are various mechanisms that enhance motor recovery after a stroke. In clinical practice, we have the opportunity to enhance plasticity by designing specific rehabilitation programs. Areas covered: There are a variety of drugs commonly administered to people after the acute phase of a stroke. These drugs may modify motor performance. Herein reviewed is the evidence concerning motor enhancement or decline in stroke patients, p...

Features and Outcomes of Methamphetamine Associated Pulmonary Arterial Hypertension.
CONCLUSIONS: Meth-APAH is a severe and progressive form of PAH with poor outcomes. Future studies should focus on mechanisms of disease and potential therapeutic considerations. PMID: 28934596 [PubMed - as supplied by publisher]

CART modulates beta-amyloid metabolism-associated enzymes and attenuates memory deficits in APP/PS1 mice.
CONCLUSION: CART decreases the levels of soluble Aβ in the hippocampus of APP/PS1 mice by modulating the expression of Aβ metabolism-associated enzymes, which may be associated with the MAPK and AKT pathways. PMID: 28743230 [PubMed - as supplied by publisher]

Noradrenergic antagonists mitigate amphetamine-induced recovery.
Abstract Brain injury, including that due to stroke, leaves individuals with cognitive deficits that can disrupt daily aspect of living. As of now there are few treatments that shown limited amounts of success in improving functional outcome. The use of stimulants such as amphetamine have shown some success in improving outcome following brain injury. While the pharmacological mechanisms for amphetamine are known; the specific processes responsible for improving behavioral outcome following injury remain unknown. Understanding these mechanisms can help to refine the use of amphetamine as a potential treatment or l...

Effects of monoaminergic drugs on training-induced motor cortex plasticity in older adults.
Abstract Primary motor cortex (M1) plasticity is involved in motor learning and stroke motor recovery, and enhanced by increasing monoaminergic transmission. Age impacts these processes but there is a paucity of systematic studies on the effects of monoaminergic drugs in older adults. Here, in ten older adults (age 61+ 4 years, 4 males), we determine the effects of a single oral dose of carbidopa/levodopa (DOPA), d-amphetamine (AMPH), methylphenidate (MEPH) and placebo (PLAC) on M1 excitability and motor training-induced M1 plasticity. M1 plasticity is defined as training related long lasting changes in M1 excitab...

Risk of stroke in prescription and other amphetamine ‐type stimulants use: A systematic review
Conclusions. This is the first systematic review on ATS and stroke. Limited epidemiological evidence suggests that ATS use increases stroke risk. Possible disparities in ATS effect across stroke type and higher effect in women deserve further clarification. Studies on non‐medical ATS use should be a priority.

Methamphetamine-related brainstem haemorrhage
We report the case of an otherwise healthy 29-year-old woman who presented with a brainstem haemorrhage following intravenous methamphetamine use. Extensive investigation did not reveal an underlying pathology, and the development of symptoms was temporally related to methamphetamine injection. Although intracerebral haemorrhage secondary to methamphetamine use is well documented, this report describes a haemorrhage within the brainstem which is a rare location. While animal studies have demonstrated the potential of methamphetamines to produce brainstem haemorrhages, there has only been one previous report describing a ha...

Illicit Drug Related Acute Ischemic Stroke, The Impact of Age and Gender (P3.236)
Conclusions: Patient age and sex are poor predictors of illicit drug related acute ischemic stroke. There is underutilization of urine toxicology screening. Acute ischemic stroke standard labs should include urine toxicology screening.Disclosure: Dr. Alhatou has nothing to disclose. Dr. Kirkman has nothing to disclose.

Intracerebral Hemorrhage Associated with Oral Phenylephrine Use: A Case Report and Review of the Literature
Conclusions: It is scientifically plausible that phenylephrine may cause strokes, consistent with the pharmacologic properties and adverse event profiles of similar amphetamine-like sympathomimetics. As RCVS has been well described in association with over-the-counter sympathomimetics, a likely, although not definitive, causal relationship between phenylephrine and ICH is proposed.

Cocaine- and amphetamine-regulated transcript peptide increases mitochondrial respiratory chain complex II activity and protects against oxygen-glucose deprivation in neurons.
This study demonstrated that cocaine- and amphetamine-regulated transcript (CART) peptide, specifically CART55-102, increased the survival rate, but decreased the mortality of neurons exposed to oxygen-glucose deprivation (OGD), in a dose-dependent manner. The above-mentioned effects of CART55-102 were most significant at 0.4nM. These results indicated that CART55-102 suppressed neurotoxicity and enhanced neuronal survival after oxygen-glucose deprivation. CART55-102(0.4nM) significantly diminished reactive oxygen species levels and markedly increased the activity of mitochondrial respiratory chain complex II in oxygen-glu...

The use of stimulant medications for non-core aspects of ADHD and in other disorders.
Abstract Psychostimulants play a central role in the management of ADHD. Here we review the evidence pertaining to the use of methylphenidate, dexamphetamine and related amphetamine salts, the prodrug lisdexamfetamine and modafinil for the management of comorbid ADHD and non-ADHD indications. There is a growing consensus that stimulant medications are helpful at improving the emotional dysregulation and lability, and oppositional and conduct symptoms that are often associated with ADHD. There is some evidence that psychostimulants may improve outcomes in those with treatment resistant depression, reduce negative s...
