AI Article Synopsis
- Cerebrolysin, derived from pig brain, contains neurotrophic peptides and was tested for its effects on stroke recovery in rat models.
- The study involved administering different doses of Cerebrolysin daily for 21 days, starting 24 hours after inducing a stroke in the rats.
- Results showed that a 2.5 ml/kg dose significantly improved sensorimotor recovery, particularly when treatment began 24 or 48 hours post-stroke, suggesting Cerebrolysin could aid neurological recovery after a stroke.
Article Abstract
Background: Cerebrolysin, a preparation derived from porcine brain, contains a mixture of neurotrophic peptides. We tested the effects of Cerebrolysin in a model of stroke recovery in rats.
Methods: Cerebrolysin (1.0, 2.5, or 5.0 ml/kg) was administered once daily intraperitoneally for 21 days, starting 24 hours after focal cerebral infarction (stroke) due to middle cerebral artery occlusion in mature rats.
Results: Enhancement of sensorimotor recovery, as assessed by forelimb and hindlimb placing and body swing tests, was seen with Cerebrolysin treatment, especially at the 2.5 ml/kg dose. At this dose, enhanced recovery was found when Cerebrolysin treatment was begun at 24 or 48 (but not 72 hours) after stroke onset. There were no effects on body weight or infarct volume when Cerebrolysin was administered in this manner.
Conclusions: These results suggest that Cerebrolysin may be a useful treatment for enhancing neurological recovery after stroke.

Background: Chronic olfactory disorders are some of the most frequent post-COVID-19 presentations. Olfactory training (OT) is currently the most popular method used for treating post-viral olfactory dysfunction (PVOD). We evaluated the effect of olfactory training on the chronic olfactory disorders of patients infected with COVID-19.

Lesions in the motor cortex induced by contusions or pathological insults can exert the degeneration of afferent neurons lying distal to these lesions. Axon degeneration and demyelination are hallmarks of several diseases sharing pathophysiological and clinical characteristics. These conditions are very disabling due to the disruption of motor abilities, with lesions that affect this area proving to be a therapeutic challenge, which has driven increasing efforts to search for treatments.

Objective: This network meta-analysis aims to explore the efficacy and safety of neuroprotective agents in patients with ischemic stroke and attempts to identify which drug is the most effective in improving outcomes for patients with acute ischemic stroke (AIS) through a ranking method.
Methods: We comprehensively searched the PubMed, Medline, Embase, Web of Science, and Cochrane library databases from their establishment to 30 June 2024. Data were extracted from the studies identified, and their quality was assessed using the Cochrane risk-of-bias tool or the Newcastle-Ottawa Scale (NOS).

This systematic review evaluates the effectiveness of various neuroprotective strategies in enhancing recovery following acute ischemic stroke, focusing on interventions such as normobaric oxygen (NBO), lithium, selective serotonin reuptake inhibitors (SSRIs), and Cerebrolysin. Drawing upon data from six primary studies, including randomized controlled trials (RCTs) and meta-analyses, we assessed these therapies' impact on functional outcomes, motor recovery, and neurological improvement. Normobaric oxygen, across 12 RCTs, demonstrated limited efficacy in improving recovery outcomes or reducing mortality.
