Peptides - Cerebrolysin

What is Cerebrolysin?

Cerebrolysin is used as a neurotrophic agent for the treatment of ischemic stroke and Alzheimer’s Disease. It is also used for as a nootropic, otherwise known as smart drugs and cognitive enhancers.

How does it work?

Cerebrolysin has been proven to have neurotrophic action similar to nerve growth factors causing peripheral and central neuronal stimulation. It improves efficiency within the brain’s aerobic metabolic processes and improves intracellular peptide synthesis. The neuroprotective properties of this nootropic agent help to shield neurons from lactocidosis, to prevent formation of free radicals and to decrease neurotoxic action of certain amino acids.


Cerebrolysin has been shown to be beneficial in treating Alzheimer’s. A review of 15 clinical trials, including 2,446 subjects, found that high doses of cerebrolysin reduced psychological symptoms and slowed disease progression in patients with Alzheimer’s disease and dementia. Cerebrolysin is a treatment used in many countries to treat strokes. In several randomized, double-blind trials of up to 28 weeks duration in patients with Alzheimer’s disease, cerebrolysin was superior to placebo in improving global outcome measures and cognitive ability.

Cerebrolysin may be beneficial for Autism as well. In a study of 19 children with childhood Autism and 8 with Asperger’s syndrome, cerebrolysin therapy improved cognitive function in all Asperger’s cases and 89% of the autism cases. In another study of 43 children with autism, 27 children showed signs of improvement after receiving the drug.

In another study of 60 children with ADHD, cerebrolysin improved symptoms in 70-80% of subjects. Cerebrolysin may also help with depression. A combination of cerebrolysin with anti-depressants was more effective in patients with treatment-resistant depression than anti-depressants alone.

Cerebrolysin can also be used as a nootropic. Nootropics are supplements that help improve cognitive functions, particularly executive functions, memory, creativity, or motivation, in health individuals. The cognitive enhancing effect of cerebrolysin is often compared to Semax, another popular nootropic agent. According to its early users, cerebrolysin immediately gives their brain an energy boost that is sustained for several hours. Users have reported better memory retention, improved focus, better learning abilities, and enhanced verbal fluency.
