Psychopathology: Person-Centered Approach and Brain Function

Introduction to Psychopathology

Psychopathology has attracted differentiated opinions from various psychologists. Warner's process of relabeling and Prouty's pre-therapy approach — which offers a pathway for the mentally unwell — are both discussed here in depth. The effects of language barriers on collaboration between psychologists and psychiatrists in delivering person-centered therapies are also reviewed. Enhanced communication between medical practitioners is fundamental for advancing scientific research on brain functionality and for developing better methods to address dysfunctional elements in human cognition and behavior. This paper examines the person-centered approach and its effectiveness in addressing brain disorders and other physical impairments.

Psychopathology is the study of behaviors, human feelings, and thoughts that either cause depression or anxiety (distress), drive individuals toward dangerous activities harmful to themselves or others, or produce rebellion and incoherence with social expectations. It also involves the study of dysfunctional traits in individuals who struggle to function in real-life situations — and combinations of all these aspects are possible. In the ancient world, psychopathology was linked to demonic powers, divine punishment, and other supernatural forces, and it consistently attracted pity and fear. Today, however, several paradigms are used to understand psychopathology, including the socio-cultural, transpersonal, biomedical, behavioral, psychodynamic, humanistic, and cognitive models (Winstead & Maddux, 2005, p. 20).

Mental health is a concept that has proven to encompass many perspectives, ranging from symptoms of incapacitation and spiritual wellness to ethical feelings and the expected, normal psychological functioning of an individual. Cultural background plays an important role in determining how people understand mental health. For instance, in many African and Asian countries, as well as parts of the Americas, an altered state of mind was not strongly stigmatized and was in fact regarded as normal in some tribal cultures. This stands in contrast to Western culture, where such experiences were regarded as abnormal and treated as illness (Lemma, 1996, p. 3).

Medical Model of Mental Health

The medical model relies on biological functioning and defines disease as the poor functioning of body organs, cells, and other body systems, including the circulatory and urinary systems. When applying the medical model, population health can be measured through vital statistics focusing on morbidity (the amount of illness) in relation to mortality rates. The model does not emphasize social factors affecting an individual's health; instead, it considers only behavioral and mental integration factors. According to this model, health is considered restored when a disease is cured or a particular affected organ regains its function. The model is limited, however, by its tendency to overlook social and psychological factors (Edlin & Golanty, 2009, p. 6).

Neurobiology is the branch of science that specializes in the study of human psychology, anatomy, and the pathology of the nervous system. This section focuses on three major functions of the brain: the neuroanatomical function, the neurochemical function, and circadian rhythms.

Neurobiology and Brain Function

Just as the cell is the basic functional unit of the body, the neuron is the basic functional unit of the nervous system. In addition to neurons, the brain contains numerous supporting cells, including vascular supply and glial cells. Neurons form a network linked by dendrites, which receive impulses originating from other neurons. Neurons also contain an axon, which transmits data to other neurons. A group of axons is referred to as a nerve, also known as a tract, which links the brainstem and spinal cord to the muscles and skin. The myelin sheath is the structure responsible for the speed and specificity of impulse transfer along the nerve. Anatomically, synapses occur only between dendrites and axons. Neurotransmitters such as dopamine are responsible for the transfer of impulses across these synapses. Neurotransmitters act locally, influencing only the dendrites near their point of release — unlike peptides, which transmit neural information to areas further from their point of origin (Gibson & Petersen, 2010, p. 13).

Many brain functions are carried out through diffuse pathways known as neurochemical processes. These pathways include dendrites and axons spread throughout the brain. To detect the functional abilities of neurons, psychoactive (neurotransmitter) drugs can be used to affect neuronal activity. This can be accomplished in two major ways, though in both cases the ligand must bind to the appropriate receptor located on the cell membrane, and the cell will respond according to the physical structure of that receptor.

The most common receptor mechanism acts quickly and directly. When transmitters bind to receptors — for example, glutamate — the permeability of the cell membrane is modified, allowing ions such as chloride to enter the neuron. This ion exchange triggers neural activity according to the neurotransmitter's properties. The second mechanism is slower, taking between seconds and minutes. It involves receptors associated with neuromodulators (such as dopamine), which affect neurons indirectly through intracellular processes. Once a neuron is bound by a neuromodulator, it responds by exposing its physiological and chemical factors. These modulators play a significant role in cognitive neuroimaging processes (Frackowiak, 2004, p. 304).

Circadian rhythms govern the cyclical changes in sensory stimulation processes. They have been frequently demonstrated in laboratory animals such as rats, but also occur in humans and some invertebrates. While many animals do not exhibit clear day-and-night cycles, they show rhythms in other ways, such as locomotive behavior. Nocturnal animals such as owls experience more active circadian cycles in darkness, while humans display their rhythms during daylight hours. Most of this process becomes routine and programmed; for example, humans have entrained to a 24-hour clock system.

Circadian rhythms are regulated by "clock genes," which have been studied extensively in insects and have also been identified in some humans. In most cases, the protein products of these genes enter their cells and regulate their activity. Because light availability provides feedback for this system, visual input is essential to maintaining the rhythms. However, not all visual information affects the rhythm — what matters is the simple reception of light by the retina (Webster, 2001, p. 478).

Conclusion

Both the medical model of mental health and the person-centered approach offer strategic ideas to help those in the psychopathology field understand the best ways to support individuals who experience mental dysfunction and other forms of impairment. The brain, though complex in its functioning, retains the capacity to regain functionality — and the person-centered approach is most ideal in this regard, as it enables the individual to restore normal functioning without necessarily requiring medical intervention. Beyond offering a less costly alternative to medical care, the person-centered approach also provides individuals with the opportunity to explore their potential, pursue their life goals through self-realization, and ultimately achieve optimal functioning.
