The electrical discharge of neurons associated with seizure activity stimulates a marked rise in cerebral metabolic activity. Estimates from animal experiments indicate that energy utilization during seizures increases by more than 200", while tissue adenosine triphosphate (ATP) levels remain at more than 95" of control, even during prolonged status epilepticus. The brain generally withstands the metabolic challenge of seizures quite well because enhanced cerebral blood flow delivers additional oxygen and glucose. Mild to moderate degrees of hypoxemia that commonly accompany seizures are usually harmless. However, severe seizures and status epilepticus can sometimes produce an imbalance between metabolic demands and cerebral perfusion, especially if severe hypotension or hypoglycemia is present. A marked increase in glutamate release, which occurs during a prolonged seizure, is likely to result in the activation of all types of glutamate receptors. Although kainic acid produces seizures in the immature brain, it produces little cytotoxicity.

- Go to chapter: Stabilization Phase of Trauma Treatment: Introducing and Accessing the Ego State System
This chapter aims to help clinicians learn stabilization interventions for use in the Preparation Phase of eye movement desensitization and reprocessing (EMDR) treatment. Using these interventions will aid clients in developing readiness for processing trauma, learning how to manage symptoms of dissociation, dealing with affect regulation, and developing the necessary internal cohesion and resources to utilize the EMDR trauma-processing phase. Earlier negative experiences stored dysfunctionally increase vulnerability to anxiety disorders, depression, and other diagnoses. When assessing a client with a complex trauma history, clinicians need to view current symptoms of post-traumatic stress disorder (PTSD) or depression as reflections of the earlier traumas. The chapter outlines the strategies dealing with dissociative symptoms, ego state work, and internal stability that help clinicians to develop an individualized treatment plan to successfully guide the client through the EMDR phases of treatment.
- Go to chapter: ACT-AS-IF and ARCHITECTS Approaches to EMDR Treatment of Dissociative Identity Disorder (DID)
This chapter describes key steps, with scripts, for the phases of therapy with a dissociative identity disorder (DID) client, and for an eye movement desensitization and reprocessing (EMDR) session with a DID client. In brief, the method employs the artful use of EMDR and ego state therapy for association and acceleration, and of hypnosis, imagery, and ego state therapy for distancing and deceleration within the context of a trusting therapeutic relationship. It is also endeavoring to stay close to the treatment guidelines as promulgated by the International Society for the Study of Trauma and Dissociation. The acronym ACT-AS-IF describes the phases of therapy; the acronym ARCHITECTS describes the steps in an EMDR intervention. Dual attention awareness is key in part because it keeps the ventral vagal nervous system engaged sufficiently to empower the client to sustain the painful processing of dorsal vagal states and sympathetic arousal states.
One way of thinking about procrastination is to regard it as a form of addiction; an addiction to putting things off. As with other addictive patterns, the client will choose a short-term gratification instead of going for a long-term result that might, in the end, be more satisfying or empowering. As with other addictions, a procrastinating client often suffers ongoing erosion of her self-esteem. Quite often, procrastination may function as a defense as a way to avoid other life issues that are disturbing. With this type of problem, we can use a variation of Popky’s addiction protocol, and the level of urge to avoid (LoUA) procedure. It is also important to use resource installation procedures to help the client develop an image of the benefits that would come with being free of this problem.
The important elements of the Eye Movement Desensitization and Reprocessing (EMDR) and Phantom Pain Research Protocol are client history taking and relationship building, targeting the trauma of the experience, and targeting the pain. This protocol is set up to follow the eight phases of the 11-Step Standard Procedure. This chapter presents a case series with phantom limb patients obtained a few before and after EMDR magnetoencephalograms (MEGs) at the University of Tübingen, Germany on arm amputees that show the presence of phantom limb pain (PLP) in the brain images before EMDR and the absence of it after EMDR. In these case series, it is found that PLP in leg amputations is much easier to treat than arm amputations, likely due to the much more extensive and complex arm and hand representation in the sensory-motor cortex compared to the leg and foot representation.
The “Image Director Technique” was developed to target recurring nightmares or bad dreams and those targets that are directly related to a traumatic experience. This technique is a special module that is embedded in the Standard Eye Movement Desensitization and Reprocessing (EMDR) Protocol. The technique begins with the worst image of the dream and then accesses and measures it as in Phase 3 of the Standard EMDR Protocol that includes the image, cognitions, emotions, and sensations. Clients are more likely to work with short clips or films if the subjective units of disturbance (SUD) of the target image is low. This technique can also be considered an imagery exposure method that is based in systematic desensitization, a behavioral approach. Often, clients prefer the tactile bilateral stimulation (BLS) because they can close their eyes in order to be visually undisturbed during the creation of the new images.
This chapter focuses on office automation and systems that are useful in the mental health field, along with principles to be aware of when considering the use or purchase of such systems. Most managers have to rely on input from outside in order to form an opinion about how to resolve complex issues. The complexity of the issue increases significantly when the current federal health care laws are incorporated into the task of choosing appropriate clinical information management software. The significance of Health Insurance Portability and Accountability Act (HIPAA) would seem to dictate at least a brief foray into its content because it lays the foundation for virtually everything that is happening in the clinical information management (CIM) realm. The information provided in the chapter can give a backdrop by which current practices can be examined for goodness of fit with the available client information management systems.
Recent advancements in molecular genetics have expanded our understanding of the etiology of many neurological diseases and neurodevelopmental abnormalities. Having a comprehensive understanding of genetics is essential in treating patients with metabolic epilepsies. Genetic counseling has been defined as a process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease. Some of the components of a genetic counseling interaction include interpretation of family and medical histories to assess the chance of disease occurrence or recurrence; education about inheritance, testing, management, prevention, resources, and research; and counseling to promote informed choices and adaptation to the risk or condition. The genetic counselor may also educate patients and their families about the underlying genetics of their epilepsy and the relevance of a genetic cause of epilepsy for family members, including recurrence risk, reproductive options and the possible teratogenic effect of antiepileptic drugs.Source:
This chapter presents a brief review of the enzymes, transporters, and cofactor producers of the urea cycle. Seizures have long been associated with urea cycle disorders (UCDs), thought to be caused by high levels of ammonia. Furthermore, the brain damage obtained during metabolic crisis has been thought to damage critical structures, leading to epilepsy after the conclusion of the crisis. The first and most critical step of successful treatment of UCDs is recognition. Neurologic monitoring is an essential part of the emergency management of UCDs. The neurological abnormalities observed in patients with urea cycle defects are vast. Controlling ammonia levels by dialysis and complementary medication are needed. EEG monitoring should be initiated early, as this may be very useful for clinical management and indication of untreated metabolic crises. Furthermore, aggressive treatment of clinical and subclinical seizure activity may be helpful in optimizing outcomes for these patients.Source:
Clinical neurophysiology (CNP) is a time-honored medical specialty that continues to make great strides, bolstered by rapid advances in neuroscience, biomedical engineering, and computer technology. It encompasses a wide range of methods and techniques for recording, presenting, and analyzing neurophysiologic signals in order to diagnose sensory, motor, autonomic, and central nervous system disorders. Testing performed in CNP or procedures used in current neurological practice include a variety of modality-specific and mixed-modality tests. Modality-specific CNP tests are performed to assess specific functional modalities using biomedical instruments that measure changes in neurophysiologic signals that occur spontaneously or with activation. Mixed-modality CNP tests utilize two or more test modalities to assess complex states (e.g., sleep, coma), to track multiple physiologic parameters, or to obtain more accurate results. CNP tests are classified based on functional anatomy or neural pathway tested. This chapter discusses artifact recognition and presents sources of artifacts in clinical neurophysiologic testing.
