[Asthenic disorders correction with Recognan]

Asthenia, asthenic syndrome, asthenic condition, asthenic reaction, asthenic disorders are terms that describe the state of «impotence». Fatigue that occurs against the background of habitual physical or intellectual stress for a person, and persists after rest, is asthenia. For people of the older age group, the term senile asthenia syndrome is used. Asthenia manifests itself with increased fatigue and exhaustion, mood instability, increased irritability, sleep disorders. Asthenic conditions manifest themselves along with a decrease in physical activity, increased cognitive and mental fatigue. Asthenic syndrome (AS) are considered as an integral part of cardiovascular diseases (CVD), as one of the manifestations of cerebrovascular pathology. Senile asthenia syndrome (SAS) is a geriatric syndrome characterized by an age-associated decrease in the physiological reserve and functions of many body systems, including cognitive functions. One of the drugs that has a positive effect on the severity of AS and improves the state of cognitive functions is the domestic drug Recognan (citicoline). The effectiveness of Recognan in the treatment of AS in patients with CVD, SAS, and post-COVID asthenia has been shown. It is recommended to prescribe Recognan orally at 500 mg / day for 30 days. Recognan has a nootropic and antiasthenic effect.

[Recognan (citicoline) efficacy and safety in cognitive impairment correction of various nosological forms]

Insufficiency of a choline derivative (acetylcholine) can lead to the development of cognitive impairment (CI). One of the most well-known and well-studied medical drugs (MD) containing choline and having neuroprotective properties is citicoline (Recognan). A number of studies have demonstrated the effectiveness of Recognan in relation to mild CI, chronic cerebrovascular diseases (CVD), acute vascular disorders (including post-traumatic genesis). Recognan improves memory and other cognitive functions in healthy young people against the background of asthenia due to stress or increased cognitive and emotional stress or infection, and also has a preventive effect on fading cognitive functions in the process of age-related changes. The duration of neuroprotection can reach 6 months or more - up to 12 months, depending on the patient's condition. Therapy regimens include two-stage Recognan prescribing: with CVD intramuscularly (i/m) at 1000 mg /d for 30 days, in the acute period of ischemic stroke, i/m or intravenously (i/v) at 1000 mg every 12 hours from the first day after diagnosis, 3-5 days after the start of therapy, with preservation functions of swallowing, it is possible to switch to per oral (p/o) drug administration.

[The effect of the use of the drug recognan (citicoline) on the state of higher mental functions in patients with mild cognitive impairment]

OBJECTIVE

The aim of the observational program was to study the effect of the use of the drug recognan (citicoline) on the state of higher mental functions (memory, attention, visual-motor coordination, dynamic praxis,verbal thinking and imagination) in patients with mild cognitive impairment.

MATERIAL AND METHODS

A survey of 54 subjects (16 of them male and 38 female) aged 18-50 years (average age 28.5±10.5 years) was conducted with a diagnosis of «Mild cognitive impairment» («F06.7»). The group was randomized into 2 subgroups: the main subgroup (26 people) received oral therapy with the drug Recognan, for 30 days, with the daily dosage of the drug being 500 mg. In the control group (28 people), nootropic drug therapy was not performed. Standard psychometric techniques were used to study higher mental functions. All subjects were examined three times (initially, in the middle of the study - on day 15, at the end of the study - on day 30).

RESULTS AND CONCLUSION

After 2 weeks of treatment with recognan, there was an improvement in concentration in 81.9%, memory in 50% (p=0.008), verbal imagination productivity in 68.2% (p=0.015), counting functions in 60% (p=0.015), visual-motor coordination and dynamic praxis - in 86.4% (p=0.003), increased speed and efficiency of mental work (p=0.001). After a 30-day course of treatment with recognan, there was an improvement in memory in 58.3% of patients (p=0.007), an increase in concentration in 64%, an improvement in counting functions in 64.3% (p=0.011), verbal imagination productivity in 63.3%, visual-motor coordination and dynamic praxis in 86.4% (p=0.007), speed and efficiency of mental work (p=0.006), which indicates a complex positive effect of recognan on higher mental functions in patients with mild cognitive impairment cognitive impairment.

[Molecular and clinical aspects of the effect of cytidyndiphosphocholine on cognitive functions]

OBJECTIVE

Systematization of the array of publications on cytidyldiphosphocholine (CDP-choline).

MATERIAL AND METHODS

Systematic computer analysis of all currently available publications on CDP-choline (1750 publications in PUBMED) using the topological theory of big data analysis.

RESULTS

CDP-choline is essential for acetylcholine biosynthesis, phospholipid metabolism, and DNA methylation. The article describes the effects of CDP-choline on acetylcholinergic and other types of neurotransmission, anti-inflammatory, neuroprotective and neurotrophic effects of CDP-choline. Also, the paper presents the effects of the molecule on lipid metabolism and gene expression within the post-genomic paradigm (in particular, an increase in the expression of nicotinic and muscarinic acetylcholine receptors). The results of fundamental and clinical studies of CDP-choline in the treatment of cognitive impairments associated with cerebral ischemia and neurodegeneration are presented.

CONCLUSION

The pharmacological effects of CDP-choline are mediated through multiple molecular mechanisms that contribute to the nootropic action of this molecule.

[The influence of the drug recognan (citicoline) on neurodynamic characteristics of mental activity in patients with mild cognitive impairment]

OBJECTIVE

The aim of the study was to study the effect of the drug recognan (citicoline) on the neurodynamic characteristics of mental activity in patients with mild cognitive impairment.

MATERIAL AND METHODS

A survey of 58 subjects (17 of them male and 41 female) aged 18-45 years (average age 27.2±12.5 years) was conducted. Clinical diagnosis according to ICD-10 «Mild cognitive impairment» (F06.7). The main subgroup included29 people received oral recognan therapy (in solution, 100 mg in 1 ml) for 30 days, with a daily dosage of 500 mg (5 ml of solution). In the control group (29 people) drug therapy was not performed. Tests were used: «Graphic sample», the sample on the reciprocal coordination of the hands (Ozeretsky test), test for the compression of fingers, the test «number series». The follow-up period was 30 days. All subjects were examined three times (initially, in the middle of the study - on day 15, at the end of the study - on day 30).

RESULTS AND CONCLUSION

The results obtained showed that the use of the drug recognan (citicoline) has a positive effect on the indicators of visual-motor coordination and spatial representations, neurodynamic characteristics of movement, and cognitive functions. After a 2-week treatment with recognan improved graphical sample, 84% of patients, with reliable improvement according to the Wilcoxon (p=0.0002), the sample in the compression of the fingers 60%, as well as coordination 60%, the accounting functions in 44%. After a month (30 day) treatment course recomanem there was an increase in indices of samples for the compression of fingers in 71.4% of patients, with significant improvement (p=0.0499) and run the graphical samples of 71.4%, coordination at 46.4%, counting functions - 48% patients.

[A personalized selection of choline precursors in evidence - based medicine]

The analysis of mechanisms of the neuroprotective effect of choline precursors reveals the primary effects of citicoline on the processes of repair of neuronal membranes, a decrease in the degeneration of free fatty acids, and choline alfoscerate, an increase in the production of the neurotransmitter acetylcholine. Although citicoline has a lesser effect on choline secretion than choline alfoscerate, the combination of choline and cytidine in its composition is a universal tool to reduce symptoms of cerebral ischemia, to stabilize cognitive status, superior to the standard benefits of choline. Various mechanisms of the action of citicoline enable to recommend it as a drug effective both in the acute phase of the disease and in the delayed period, giving it the status of a universal nootropic compound.

[Features of positive personality phenomena in patients with mild cognitive impairment and asthenic syndrome treated with recognan (citicoline)]

AIM

To assess the formation of positive personality phenomena in patients with mild cognitive impairment and asthenic syndrome during the treatment with recognan (citicoline).

MATERIAL AND METHODS

Thirty-eight patients (17 men and 21 women), aged 18 to 45 years (mean age 27.8±12.1 years), with asthenic syndrome with mild cognitive impairment (ICD-10 F06.7) were examined. Patients were divided into two groups: 20 people in the main group and 18 people in the comparison group. The main group received recognan (orally, in solution, 100 mg in 1 ml) for 30 days, the daily dosage of the drug was 0.5 g (5 ml solution). The comparison group did not receive any medications. Adapted methods of positive personality psychology were used: the Fordyce Emotions Questionnaire, the Subjective Happiness Scale (SHS), the Adult Hope Scale (AHS), the Satisfaction with Life Scale (SWLS), M. Atkinson's Scale of Emotional Maturity, the projective technique 'Map of experiences'. The follow-up period was 30 days. All subjects were examined three times (at baseline, 15 and 30 days after treatment).

RESULTS AND CONCLUSION

After a month of treatment with recognan, there was an improvement of positive personality traits and a significant decrease in negative experiences, indicating the positive impact of the drug on the formation of positive personality manifestations and compensation for emotional disorders in patients with mild cognitive impairment and asthenic syndrome.

[Current treatment options for autonomic, cognitive and emotional disorders in patients with asthenic syndrome treated with recognan (citicoline)]

AIM

To study the efficacy of recognan (citicoline) in the treatment of cognitive, emotional, autonomic, asthenic disorders in patients with asthenic syndrome.

MATERIAL AND METHODS

Thirty-eight subjects (17 men and 41 women), mean age 27.75±12.05 years, with asthenic syndrome (ICD-10 F48.0 - Neurasthenia) were studied. The sample was randomized into 2 subgroups: the main group (n=20) received oral therapy with recognan (100 mg in 1 ml) for 30 days, while the daily dosage was 500 mg (5 ml). In the control group (n=18), no drug therapy was performed. Patient's state was assessed with a large battery of psychological tests and psychometric scales. The follow-up period was 30 days. All participants were examined three times (initially, in the middle of the study (day 15), in the end of the study (day 30)).

RESULTS AND CONCLUSION

Asthenic syndrome was detected in 100% of the patients (total asthenia was noted in 70%, decreased activity in 70%, decreased motivation in 40%, physical asthenia in 45%, mental asthenia in 50%). Recognan (citicoline), used for 2 weeks or one month, has a positive effect on the compensation of autonomic, asthenic cognitive and emotional disorders and increases stress resilience of the patients.

[Impairments of cognitive control in patients with somatoform disorders and their treatment]

AIM

To study impairments of cognitive control in patients with somatoform disorders (SD) and to evaluate the efficacy of recognan in the treatment of this pathology.

MATERIAL AND METHODS

Forty-six patients with SD, aged from 18 to 45 years, were studied. A clinical history, neurological examination, and assessment of autonomic disorders were collected from all patients. For the objectification of the severity of asthenic and emotional disorders, the Subjective Scale of Asthenia (MFI-20), the Hamilton Anxiety Scale (HARS), the Cognitive Emotion Regulation Questionnaire (CERQ were used. A quantitative assessment of impaired attention and impulsivity was performed using the psychophysiological test TOVA. Patients were treated with recognan (citicoline). The control group consisted of 30 healthy people aged from 18 to 45 years.

RESULTS AND CONCLUSION

Patients with SD had specific characteristics of the cognitive sphere, most pronounced in the form of attention disorders. The psychological study showed the higher level of anxiety. In addition, patients with SD were characterized by the low levels of emotional intelligence and cognitive control of emotions compared with the control group. The results of the follow-up study after treatment suggest the high efficacy of recognan in the treatment of SD (improvement was noted in 67.4% of patients). A significant decrease in the severity of autonomic disorders and in indicators characterizing asthenia was established after the treatment.
