What is psychiatry

What is Psychiatry?

  • A specialty of medicine…

  • Dealing with dysfunctions and illness…

  • That affect behavior, mood, thought and perception…


What is the organ of psychiatry

What is the “organ” of Psychiatry?

Houston…

1.We’re not urologists

2. We’re not cardiologists


The human brain

The Human Brain

  • 100 billion nerve cells-mostly neurons

  • Hundreds of trillions of synapses

  • 60 known neurotransmitters

  • 300 putative neurotransmitters

  • Enzymes

    • Synthesis

    • Degradation

  • Transport mechanisms, storage, and release

  • 2 to 10+ receptor subtypes

  • Second messenger systems

  • Ion channels-binary action potentials of axons


The dsm iv tr

THE DSM-IV-TR

  • Utilizes objectifiable clusters of signs and symptoms

  • To define specifically over 300 psychiatric illnesses

  • Common diagnostic language worldwide among mental health professionals


Biopsychosocial approach

Biopsychosocial Approach

1.Biological features

  • Genetic predispositions

  • Brain lesions and disorders

  • Endocrine dysfunctions

  • Toxins (e.g. alcohol)

  • Somatic disorders (e.g. diabetic Ketoacidosis)

The human costs of mental illness and addictive disorders stigma

The Human Costs of Mental Illness and Addictive Disorders -Stigma-

Stigma

Stigma, fear, and embarrassment are universally associated with mental illness.

Many Americans with treatable psychiatric disorders refuse to seek care.


A survey conducted by the national mental health association nhma of 1022 adults found

A survey conducted by the National Mental Health Association (NHMA) of 1022 adults found:

1.Half of American adults reported that they or a family member have suffered from depression.

2.Forty-three percent see depression as a “personal weakness,” with another 11% uncertain whether it is a personal weakness or a health problem.

3.Two-thirds of those suffering from depression will not seek treatment.

The good news about mental illness and psychiatry

The Good News About Mental Illness and Psychiatry

  • Through neuroscience discovery, important knowledge is being gained about the causes and effective treatments of psychiatric disorders.

  • Examples: 70% of the people with manic depression respond dramatically to lithium treatment.

  • The use of lithium has been estimated to have saved $6.5 billion annually in treatment costs alone.


The good news about mental illness and psychiatry1

The Good News About Mental Illness and Psychiatry

  • Between 80-90% of individuals suffering from major depression respond fully to psychiatric treatment that includes both medications and counseling.


The good news about mental illness and psychiatry2

The Good News About Mental Illness and Psychiatry

  • Increasingly neuroscience research is shedding light as to the causes of such illnesses as Alzheimer’s disease, schizophrenia, and even alcoholism and other substance use disorders.

  • These discoveries open the way to innovative pharmacologic and other types of biological interventions.


The promise of biological research

The Promise of Biological Research

1. Genetics

  • Localization on chromosomes of the genetic bases of specific psychiatric illness

  • Unlock physiological processes by which genes “trigger” psychiatric disorders

  • Development of tests to diagnose people at risk of transmitting severe psychiatric disorders

    d.Development of more specific interventions


The promise of biological research1

The Promise of Biological Research

2. Neuroscience Discovery

a. Major technological advances in neuroscience research will be applied to psychiatric questions such as the development of pharmacologic and electrophysiologic treatments.

b.Example-Deep Brain Stimulation for major depression and OCD.


The promise of biological research2

The Promise of Biological Research

3. Brain Imaging

a.Magnetic Resonance Imaging (MRI)

b. Regional Cerebral Blood Flow (RCBF)

c. Positron Emission Tomography (PET)

d. Single Photon Emission Computer Tomography (SPECT)
