Women with polycystic ovary syndrome (PCOS) have an increased risk of developing depression, according to a meta-analysis. “The results highlight the importance of screening for mood disorders in all women with PCOS,” the authors say.

But the team of Dr. Anuja Dokras, University of Pennsylvania, Philadelphia, admits that he has too much data to back this advice. “One longitudinal study addressed this issue. Therefore, there is a tacit recommendation, but the meta-analysis suggests that we should start to be screening all women with PCOS,” said Dokras this wording.

As published by Obstetrics & Gynecology, the researchers examined the records of abnormal depression through a systematic review and meta-analysis of 13 studies on 522 women with PCOS and 475 healthy women (control group).

The risk of getting a record abnormal depression was 4.03 times higher in women with PCOS than in control groups. In five studies that controlled for body mass index, the risk of getting an abnormal record remained significantly higher (4.09 times) in women with PCOS.

This persisted regardless of the screening tool used and country of origin of the results. Dokras said that further studies to investigate the effects of thinning on the records of depression in women with PCOS.

Why so clearly understood even remotely what we can see?
How can such complex interpretations of issues in a matter of seconds?
Why they are geniuses and not us?
BBC Focus magazine investigates.

Cortex
Normal: In the various regions of the brain of an average person establishes the same proportion (50:50) of long and short connections, with very slight variations from one individual to another.
Genius: The brain of a genius is deeply predisposed to having long or short connections.
Short connections indicate a special talent to a particular interest, while long connections suggest that there are skills in many areas of interest and there is the ability to see problems from new perspectives.

Frontal cortex
Normal: The frontal cortex, which is linked with abstract thoughts, is made of miniature columns.
Brain tissue are units that usually have between 80 and 120 neurons.
Genie: The brains of geniuses have a dense concentration of minicolumns that the brains of the rest of the population. It’s like they just assimilate more information.
These tiny columns are sometimes described as the microprocessors in the brain. It is the source that feeds the brain’s thinking process.

Dopamine receptors
Normal: The thalamus, which is the information relay center of the brain, acts as a filter.
The information or stimuli coming from the various sensory parts of the brain must pass through to the thalamus, which, once processed, are sent to the cortex.
Part of this process is partially regulated by dopamine receptors.
Genie: Scientific research shows that geniuses have fewer dopamine receptors in the thalamus. Dopamine inhibits neural signals override the information it deems worthless.
The scarcity of these receptors in geniuses would explain why spirits may consider unusual solutions to a problem that normal brains overlooked or ignored.

How likely a person with Parkinson’s disease may die than those without this disease? This recurring question gives an answer to an article published in Neurology. The retrospective study was conducted in Norway in 230 people with Parkinson’s disease followed for some years. The information was processed with multivariate analysis.

The study found that the risk of mortality increases by 1.89 times if any dementia, 1.45 in the presence of psychosis, of 1.18 times in severe motor impairments. These factors are potentially modifiable. As for the non-modifiable factors we have seen that the risk increases by 1.40 times in relation to age at onset (older you are, the greater), 1.51 in relation to chronological age, 1.63 times in males.

The hallucinations are more important than benign hallucinations, there are no correlations with antiparkinsonian drugs, or antipsychotics, or with individual motor symptoms, except with postural instability and gait disorders (increased risk of 1, 70).

The authors suggest that to increase life expectancy in Parkinson’s disease are vital to early prevention of disability and motor development of dementia and psychosis. Since no single factor has shown a very significant effect and Parkinson’s disease itself is not a deadly disease, confirming the notion that life expectancy in Parkinson’s disease is linked to overall health than the disease itself.

Importance of chronic migraine in a general neurology

Chronic migraine is a difficult to treat primary headache that produces great impact on quality of life of patients. The international classification of headache changed the criteria for chronic migraine recently, so there are few studies that analyze groups with these new criteria. Objective. Analyze a group of patients with chronic migraine referred to a general neurology. Patients and methods. We selected the first 100 patients with migraine. Were established and analyzed subgroups of patients with episodic migraine, probable chronic migraine or chronic drug abuse according to the classification of headaches of the International Headache Society (IHS) and its revision in 2006. Results. Of the total of 738 new patients, 100 (13.5%) had migraine. Of the 100 new patients with migraine, 42 (5.6% of the total series) met the criteria for chronic migraine, and 15 patients with chronic migraine, the criteria for probable medication overuse headache. Before going to the neurology, only 41% had been diagnosed with migraine, 38% had not received information about this institution, only 17% took triptans as symptomatic treatment, and 23% had continued preventive treatment. Conclusions. We emphasize the importance of episodic and chronic migraine in a general neurology, using recent criteria of the IHS. Patients with chronic migraine sent to the neurology follow, a high percentage, without being diagnosed or reported, or treated properly, with a high degree of self-medication and frequent abuse of drugs. Triptan treatment in migraine prevention and heavy are still used little in primary care.

Fetal neurological evaluation

Review recent advances in procedures and techniques that have allowed us to study the anatomy and function of the central nervous system (CNS) in the fetus. Development. The neurological evaluation of the fetus can be done from the standpoint of clinical, anatomical or functional. Clinically, the assessment of fetal body movements, eye and breathing and heartbeat, can define four fetal behavioral states: 1F and 2F correspond to the states of quiet sleep and active. 3F and 4F states exist in a state of wakefulness in the newborn, but there is no scientific evidence that the fetus has the ability to stay awake. The behavioral states probably play an important role in the maturation and development of the CNS. The anatomical evaluation of the CNS to diagnose if it can be malformed ultrasound from week 7-8 of gestation, and magnetic resonance imaging (MRI) from week 18-20. Both techniques are also useful in the diagnosis of fetal neurological diseases acquired. Both methods are consistent in most cases, but in others each provides additional, different. Computed tomography should be used only in very specific cases involving bony structures. Functional evaluation of the fetus can be done with magnetic resonance spectroscopy, which analyzes the brain content of inositol, choline, creatine and N-acetylaspartate. Other techniques for the functional study of fetal brain are functional MRI, spectroscopy, near infrared light beam and magnetoencephalography. Conclusions. The fetal neurology is a discipline that will continue its rapid development in the immediate future. Technological advances will encourage more rapid and accurate diagnosis of anatomical and functional fetal CNS.

What knowledge should be acquired neurological a medical student

Knowledge and skills to analyze neurological medical student should acquire during the undergraduate learning. Development. Was performed by a Medline search, review of neurological knowledge and skills that medical students should acquire during the undergraduate learning. Also carried out the analysis of neurological programs in 28 sites of the Spanish universities with undergraduate medical.
In accordance with the recommendations of major international neurological societies during the undergraduate medical students must learn the skills to conduct a proper clinical examination and neurological impairment and to initiate appropriate investigations and therapy of neurological diseases more frequent, urgent and treatable. Also the student should be aware of situations in which it is appropriate to seek a neurological consultation with a specialist. We discuss the multiple learning strategies to acquire these skills. The information obtained from the web shows several inadequacies with the international recommendations and support the assertions of the White Paper on undergraduate medical education of the need for reform of undergraduate education in Spain. Conclusions. Neurologic education of medical students in Spain must be transformed to adapt to international recommendations.

When we suffer a depression, it can be treated with medication, psychotherapy or a combination of both. Normal, especially when we go to the doctor for the first time, we prescribe a treatment with antidepressant drugs can improve our mood and, thus, make more effective therapy to help overcome it.

If you advise us to submit to treatment with antidepressants, although we are reluctant to take medications, we must not forget that the sooner we start the treatment under the chances that the disease is chronic. The main function of these medications is to improve our mood for that way we can confront and overcome the disease.

The main types of antidepressants are:
