Are you ready to download this book ?? Fundamental Neuroscience for Basic and Clinical Applications 5th Edition 2018 The brainstem is a phylogenetically ancient organ that subserves control of basic functions such as breathing, cardiovascular function, consciousness and thermoregu- lation. It also acts as a pathway for tracts between the cere- brum and the spinal cord controlling movement and sensation. Finally, it is involved in movement and sensa- tion of the head and neck. Examination of the brainstem provides important prognostic information in the uncon- scious patient and irreversible damage to the brainstem is the criterion for the legal definition of death.

Memorizing the Cranial nerves was bit difficult but now when you are a resident this book might help you with your Neurological condition.
To test the olfactory nerve, first ask the patient about any recent change in the sense of smell or taste. A characteristic-smelling object (e.g. peppermint, clove oil) is held under each nostril in turn while the other is occluded and the patient keeps the eyes closed. An individual who has intact olfaction can not only detect the smell but also discriminate and name it. The recommended special testing bottles are rarely avail- able when needed and most clinicians perform prelim- inary assessment with nearby objects such as fruit, a coffee jar or cigarette packet. Avoid using irritating odours such as ammonia or camphor because these can non-specifically activate fifth nerve receptors in the nasal mucosa. Unilateral loss of smell is usually asymptomatic.
Bilateral loss of smell may be associated with an altered sensation of taste (dysgeusia or ageusia). When examining patients who have anosmia, it is important to look carefully for frontal lobe signs and evidence of optic nerve or chiasmal damage, as these structures are anatomically close to the pathways that subserve smell. The most common cause of impaired smell is pathol- ogy in the nasal passages or sinuses.
