When looking at the concept of brain disorders, there are numerous illnesses that stand out. In this case study, however, we shall be focusing on Arteriovenous Malformations.
Concept of Brain Disorders
The brain acts as the primary control center of the body and regulates various body organs and functions. The brain controls movement, speech, memory, and thoughts, among others. Different factors can cause a brain disorder, and each present according to the cause. Most brain disorders will occur mainly if there is a head injury, bleeding into the brains, or malformations in the blood vessels. This can lead to symptoms like loss of consciousness, vision, headache, and photophobia, among others.
Disorders that lead to bleeding into the brain tissues can lead to an increase in the intracranial pressure, which presents with severe headaches, blurred vision, vomiting, etc., as in Chandra et al. (2017). Click here to see a custom paper on understanding brain disorders..
Solomon & Connolly (2017) postulated that in arteriovenous malformation (AVM), blood vessels are abnormal, snarled, and tangled and cause irregular connections between the veins and the arteries.
In this malformation, blood from arteries bypasses the tissues and go directly into the veins. Some small and weakened blood vessels may break and leak blood into
the brain tissue, causing stroke or damage. The individual can also develop other neurological
problems like headaches, weakness, seizures, pain, and problems with speech, vision, or
movement, as in the case of Fifty-four-year-old Fred. Headaches and seizures are always the
typical and severe symptoms of AVMs, and the severity of the headaches always depends on the
duration and intensity. Click here to see a custom paper on alzheimer’s disease.
Chandra et al. (2017) stated that cerebral circulation is mostly composed of the supplying
arterial circulation and the venous circulation that moves blood away from the brain. The
circulation can be subdivided into posterior and anterior circulation. The affected part of the
cerebral circulation is the posterior circulation. These circulations functions to main most of the

critical functions of the central nervous system. It is also known as the Verterbrobasillar
circulation and consists of vertebral arteries and the basilar artery. This circulation distributes
blood to the occipital lobe and most parts of the brain stem (anterior and posterior portions), and
all of the cerebellum. According to Natali & Leo (2018), the middle meningeal artery breaks off
the maxillary artery and takes blood to the dura mater, and its branches also supply blood to the
periosteum. The artery is close to the skull; hence it can easily be injured if there is a trauma.
Leaking of the blood from this artery can lead to an epidural hematoma that also presents with
headaches and migraines.
