Antiepileptic drugs: review of safety of use during pregnancy
Two recent Reddit discussions – both centered around CerebrumIQ results – highlight how a seemingly simple test score can lead to complex self-reflection, especially when it intersects with profession or identity. As more people search for Cerebrum IQ reviews, what they’re often really looking for is reassurance that their intelligence isn’t being misjudged – or worse, misused. A safety signal is defined as the information suggesting a new potential association or new aspects of a known association between medicines and adverse event(s) that warrant further investigation. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. Neuropathic pain is the nerve pain that is experienced by those who have peripheral neuropathy.
Dyspraxia, also known as developmental co-ordination disorder (DCD), is a common disorder that affects movement and co-ordination. It can affect co-ordination skills –such as tasks requiring balance, playing sports or learning to drive a car – and fine motor skills, such as writing or using small objects. Non-clinical studies in several animal species have reported reduced fetal bodyweight gain and a reduction in growth parameters in the fetus as well as reductions in maternal bodyweight gain. No clinical studies have examined the effect of exposure to zonisamide during pregnancy on the neurodevelopment of children.
Non-clinical studies have reported that exposure to lamotrigine during pregnancy and also in juvenile rats can induce some neurobehavioural effects at doses relevant to human therapeutic doses. NICE guidance recommends that it can be used as adjunctive treatment in focal seizures. Data from the CPRD suggests that among the prioritised antiepileptics drugs that gabapentin is one that is commonly initiated in women of childbearing age with epilepsy and also that it is among the most commonly prescribed antiepileptic drugs in pregnancy.
Given the cerebrumiq limited data, no firm conclusions can be drawn with regards to the safety of use of these antiepileptic drugs during pregnancy and the risks remain unclear. Non-clinical studies report reduced fetal body weights in rats and rabbits following exposure to pregabalin during pregnancy but this occurred at plasma concentrations sufficiently higher than human therapeutic concentrations. Dosing of pregabalin during gestation and lactation induced offspring developmental toxicity in rats at exposures 5 times or greater than the maximum recommended human exposure. A further study by Trivedi et al 2018 in the Kerala Pregnancy Registry investigated spontaneous fetal loss in pregnancies exposed to phenytoin compared with pregnancies in non-exposed women with epilepsy.
These can have different causes, including a person’s genetics, a structural change in the brain, or as a result of other health conditions. The Triune Brain We have three-brains-in-one which represents an evolutionary inheritance. This controls our basic instincts – breathing, heart rate, sense of territory. This controls our emotions, sexuality, sleep and immune system, and plays an important role in long term memory. This comprises a two-sided cerebrum the so-called left and right brain linked by a massive bundle of nerves, the corpus callosum, comprising some 200 million fibres.
Simply doing things does not require much interplay between your neo-cortex and your memory database. Unfortunately, this research only looks at the cerebral cortex; cerebro-cerebellar connectivity and the thickness of the cerebellar cortex was not included in their fMRI data. That said, the researchers thoroughly investigated the relationship between the cortical thickness across the entire cerebral cortex and the resting-state functional connectivity between 200 distinct brain regions within the cerebrum based on data from the human connectome project (HCP). Profound Multiple Learning Disabilities (PMLD)PMLD is another term to separate the most severely learning delayed from others with learning delays, so that support can be matched. Anything that means learning is severely affected can be included in this group. PMLD indicates a severe level of need, but little more as the subject is so vast.
- While the evidence to support an increased risk of major congenital malformations is not consistent across all studies, those that do not suggest an increased risk tend to be studies with a smaller number of pregnancies exposed to topiramate.
- Consequently, the available non-clinical and clinical data has been reviewed in order to determine whether the accumulating data raises any new safety concerns or changes the current understanding about the safety of use during pregnancy of these prioritised antiepileptic drugs.
- When we “have a go” at something new, we step to the edge of our existing frame of reference and we take risks (for example of looking foolish) and we may “fail”.
- A study in which a number of similar people are randomly assigned to 2 (or more) groups to test a specific drug, treatment or other intervention.
- When we are born, our brains contain a load of neurones which begin to form connections (synapses) or are removed, making the brain more organised and allowing our visual system to develop.
Fetal head circumference
They were the first to discover the presence of ocular dominance columns and they determined that both right and left ocular dominance columns exist which are stimulated by visual input from the right and left eyes respectively. As you craft your story, conjure up vivid images of each word, along with the setting of your story. As described in my last post, visualization will add the unsurpassed power of your visual brain—with it vast array of visual memory circuits– to that of your storytelling brain. Notice how easily, when you’re finished creating the story, it is to recall the story and the words woven into it, especially when you remind yourself of the “moral” of your story, which gives it both importance and meaning. Cerebral hemispheres continue with development during the 9th and 10th weeks of pregnancy.
Learning Styles and Preferences
The studies contain limited numbers of exposed pregnancies and for the studies that suggest an increased risk it is considered that the results may be affected by confounding. Clinical studies examining the effect of polytherapy are more limited and are restricted to data from the UK Epilepsy and Pregnancy Registry and the Australian Pregnancy Registry, involving more than 300 exposed pregnancies. Non-clinical studies in the published scientific literature in rodents showed neurodegenerative changes in the cerebral cortex and hippocampus of fetuses exposed to gabapentin during early and mid-pregnancy (Prakash et al 2008 and Badawy et al 2019). However, limitations in the design of these studies make them insufficient to determine the effects of gabapentin on the developing nervous system. An unpublished Good Laboratory Practice compliant study in pregnant rats showed non-dose-related behavioural changes in the performance of the offspring during tests of activity and emotionality but the changes were not statistically significantly different from those of the control animals. Overall, the non-clinical data does not provide clear evidence that exposure to gabapentin during pregnancy adversely affects the development of the central nervous system.
Connectivity of Brain Regions Matters More Than Once Thought
Professor Robin Morris is a clinical-academic neuropsychologist at the Institute of Psychiatry, Psychology & Neuroscience (IoPPN). He has conducted research mainly into consciousness, memory and executive functioning in a range of neurological and psychiatric disorders. His work has encompassed dementia, cerebrovascular disorder, epilepsy, attention deficit hyperactivity disorder, psychosis and eating disorders. As part of his research, he developed the Cognitive Awareness Model (CAM), which provides explanations of lack of awareness of disability in patients with neurological disorder. A group of disorders characterized by delays in the development of socialization and communication skills. Parents may note symptoms as early as infancy, although the typical age of onset is before 3 years of age.
