The author would like to correct the following errors in the online publication of the article:

In page 1, under the Abstract section, line 14 should read as “Two different doses of the studied specimens based on previous comparative studies and two different routes of administration (oral and intraperitoneal) were used”.

Under the Introduction heading, line 3 should read as “Cognitive disorders affecting memory and learning abilities normally occur in the process of aging, mild cognitive impairment and in Alzheimer’s disease (Lindeboom and Weinstein 2004; Pepeu 2004).”

Under the Introduction heading, line 32 should read as “Positive results of preliminary clinical trials on patients with Alzheimer’s disease, in which from a total of 15 patients receiving oral CLN at a dose of 100 μg, eight improved according to the MiniMental State Examination, while disease symptoms stabilized in the remaining seven patients (Leszek et al. 1999).”

The corrected Keywords section should read as follows:

Keywords Immunomodulatory peptides · Chicken egg yolk · Colostrinin · Coloco · Learning · Memory · Dementia · Age-related disorders · Cognitive deficits · Yolkin
