Bipolar Depression and Bipolar Affective Disorder - How Are They Related?

Bipolar affective disorder, sometimes referred to as manic-depressive illness, is a complex and chronic disease of the brain that is characterized by an interplay of hypomanic (mixed) bipolar disorder, mania and depressive (or bipolar depression) phases, with significant emotional and physical subsyndromals that often present between major depressive episodes. In addition, bipolar affective disorders can have specific types or phases. The classic type is depression, which affects about one in five Americans, and is characterized by sadness, usually lasting for longer than two weeks. This type of depression has a poor prognosis, and patients who are diagnosed with it are at high risk for suicide. The bipolar type of depression is characterized by either brief periods of mania lasting several months or the development of hypomania. In some patients, either phase of bipolar depression can be triggered by stress; others to develop the condition due to traumatic life experiences. Mani...

Basic Types of Skin Cancer

There are several different types of skin cancer, all of which may appear differently on your body. For this reason, it's important to visit your doctor when you've got any moles, lumps, spots, blisters, sores, spots, or anything else on your skin that bother you for some reason, or that you believe might be cancerous. In the past, doctors used X-rays and MRIs to determine whether skin cancer was present, but more recently, molecular imaging has proven to be even more effective in this regard. This means that your doctor can check for these types of abnormalities more quickly and easily than he or she could in the past. | There are three types of precancerous skin disease that you should be aware of. They are generally classified as either squamous cell carcinoma (SCC) or melanoma. These two cancers usually develop on the epidermis, which is the top layer of the skin's outermost layer. Melanoma is not always cancerous, although it will tend to spread much faster than SCCs w...

What Are the Most Common Symptoms of Panic Attacks in Loved Ones?

A panic attack is a sudden, intense, uncontrollable wave of panic-like fear characterized by its debilitating, suddenly immobilizing intensity and its unexpectedly suddenness. You might feel dizzy, your heart races, you can barely breathe, and you might feel like you're going crazy or dying. Panic attacks can occur out of nowhere, without warning, and in some cases with no obvious trigger. What causes them and how to control them, are the questions that beg to be answered. Like many conditions, panic attacks are generally of two types: the anxiety type and the phobic type. The anxiety type manifests itself through a host of symptoms such as chest pain, difficulty breathing, trembling, hot flashes, dry mouth, and feelings of impending doom. In the case of anxiety, these symptoms might be triggered by an imagined or actual stimulus (such as the feeling of being watched when walking alone at night). When it comes to phobia, on the other hand, the symptoms are much more concrete and pr...

Height and Horizon Line in Astronomy

Angle of depression refers to the angle between the actual object and the horizontal line of vision. It's calculated by dividing the actual viewing angle by the horizon line. For example, if the man stands 50 feet away from the edge of a building, his angle of depression would be 50 feet. In engineering and architectural terms, the term of the angle of depression is referred to as the hull angle. This refers to the angle between the actual object and the hull or the bottom of the hull. The formula for calculating the angle of depression is simple. It can be derived using trigonometric tables (which can also be purchased commercially). The formula can be written as follows: h = (sin(x+pi/3) + sin(x+r) /sin(x-ft), where r is the radius of curvature of the earth, h is the distance from the observer on the ground, and t is time. The formula is used in many engineering and constructional applications. Sine wave analysis is another method that can be used to determine the angle of the ho...

The Difference Between a Panic Attack and an Anxiety Attack

While you might have just experienced one of those crippling attacks yourself, the difference between a panic attack and an anxiety attack is actually quite difficult to decipher. The difference between a panic attack and an anxiety attack is actually quite difficult to decipher if you're not certain what to look out for. To understand this, you need to understand what a panic attack is and how it differs from an attack of anxiety. The difference between the two lies in the causes and the triggers involved in a panic attack. One of the biggest differences between panic attacks and anxiety attacks is that the first one typically begins without any particular reason. This is because it generally isn't until the brain learns that there is a real threat that the paralyzing fear starts to set in. A panic attack however, on the other hand, is triggered by an actual threat that seems to be so real that the threat itself becomes real to the sufferer's body. This gives panic attacks...
