Essay / Research Paper Abstract
This 7 page paper considers the broad origin of mental health problems and the way there may be some impair or disrupted brain function. The paper then goes on to explore dementia, looking at the variety of causes that can result in the disruption of the brain causing dementia as a symptom. This is then applied to the case of an elderly women and other issue of nursing are then considered at the end, such as the legal requirements (according to UK law) and holistic considerations.

manifest and consider the complexity of the brain as a foundation for the origins of mental illness. The human brain, which controls behaviour, is a complex organism with roughly
100 billion neurons, or nerve cells, as well as many supporting ganglia (von Bohlen, 2002). The communication within the brain takes place with a range of techniques. Communication takes place
between small structures know as synapses, this is usually in two parts, the first part of the synapse specialises in sending a signal with the use of chemicals, also known
as neurotransmitters, this is the pre-synaptic structure, the second part, the post synaptic structure has receptors to receive the communication of the neurotransmitter (von Bohlen, 2002). These are the
structures that are responsible for the communication and a small part of a much larger and more complex system (von Bohlen, 2002). The
single neuron itself may be part of several communications circuits which are organised in parallel and may be seen as a parallel distributed information processor (von Bohlen, 2002). An
example may be that for vision there is a circuit where the information seen by the retina is transmitted to the brain where, after an initial stage of processing the
information will be divided up, for example, one stream of information may concern colour, one may concern the shape in space, and the visual information is re-synthesised (Sacks, 1986). The
system is also one that has a high level of tolerance for failure, able to fill in any blanks. However this can go wrong, and identification may end up showing
an object other than that which is really observed (Sacks, 1986). Where we seen mental illness there is a disruption of the
