Post-traumatic stress disorder is a mental health disorder triggered by a terrifying event either experiencing it or witnessing it. Most people who go through mental health disorders or any traumatic events may have temporary difficulty adjusting and coping, but with time and good self-care, they usually get better.
The symptoms of PTSD a mental health disorder may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. If the mental health disorder symptoms get worse, last for months or even years, and interfere with a patient’s day-to-day functioning such person may be suffering from post-traumatic stress disorder.
Mental Health Disorder Symptoms
If you have a loved one with any of the following mental health disorder symptoms, make sure such person visit a primary care provider or mental health professional. Most mental health disorders illness doesn’t improve on their own, and if untreated, a mental health disorder may get worse over time and cause serious problems.
Examples of signs and symptoms of mental health disorders include
- Feeling sad or down
- Suicidal thinking
- Sex drive changes
- Excessive anger, hostility or violence
- Withdrawal from friends and activities
- Significant tiredness, low energy or problems sleeping
- Detachment from reality (delusions), paranoia or hallucinations
- Inability to cope with daily problems or stress
- Confused thinking or reduced ability to concentrate
- Excessive fears or worries, or extreme feelings of guilt
- Extreme mood changes of highs and lows
- Trouble understanding and relating to situations and people
- Problems with alcohol or drug use
- Major changes in eating habits
Sometimes mental health disorder symptoms appear as physical problems, such as stomach pain, back pain, headaches, or other unexplained aches and body pains.
A recent publication on the Depression and Anxiety journal studies found that an Artificial Intelligence tool can distinguish with 89% accuracy between the voices of those with or without post-traumatic stress disorder.
Use of Speech Recognition Software
Speech-based characteristics can be used to diagnose mental health disorders and post-traumatic stress disorder related illnesses. It has been confirmed that more than 70% of adults globally are experiencing a traumatic event at some point in their lives, with up to 12% of people in some struggling countries suffering from mental health disorders.
Those with the condition experience strong, persistent distress when reminded of a triggering event. According to a study, mental health disorder diagnosis is most often determined by clinical interview or a self-report assessment, both inherently prone to biases.
This has led to efforts to develop objective, measurable, physical markers of post-traumatic stress disorder progression, much like laboratory values for medical conditions, but progress has been slow.
Another research through a statistical/machine learning technique, called random forests, claimed the ability to “learn” how to classify individuals based on examples. Such Artificial Intelligence programs build “decision” rules and mathematical models that enable decision-making with increasing accuracy as the amount of training data grows.
The researchers recorded standard first, hours-long diagnostic interviews, called Clinician-Administered PTSD Scale, or CAPS, of 53 Iraq and Afghanistan veterans with a military-service-related mental health disorder, as well as those of 78 veterans without the disease.
The recordings were then fed into voice software from SRI International the institute that also invented Siri to yield a total of 40,526 speech-based features captured in short spurts of talk, which the team’s AI program sifted through for patterns.
The random forest program linked patterns of specific voice features with post-traumatic stress disorder, including less clear speech and a lifeless, metallic tone, both of which had long been reported anecdotally as helpful in diagnosis.
While the current study did not explore the disease mechanisms behind post-traumatic stress disorder, the theory is that traumatic events change brain circuits that process emotion and muscle tone, which affects a person’s voice.
Mental Health Machine Learning Projects
Application of Artificial Intelligence voice tool with more data. The research team plans to train the Artificial Intelligence voice tool with more data to further validate it on an independent sample, and apply for government approval to use the tool clinically globally.
The lead author is Adam Brown, PhD, adjunct assistant professor in the Department of Psychiatry at NYU School of Medicine. said;
“Speech is an attractive candidate for use in an automated diagnostic system, perhaps as part of a future post traumatic stress disorder smartphone app, because it can be measured cheaply, remotely, and non-intrusively,”
Dimitra Vergyri, director of SRI International’s Speech Technology and Research (STAR) Laboratory, said;
“The speech analysis technology used in the current study on PTSD detection falls into the range of capabilities included in our speech analytics platform called SenSay Analytics.
“The software analyzes words — in combination with frequency, rhythm, tone, and articulatory characteristics of speech to infer the state of the speaker, including emotion, sentiment, cognition, health, mental health and communication quality. The technology has been involved in a series of industry applications visible in startups like Oto, Ambit and Decoded Health.”
