2 times this year i have smelled a cemichal smell that lasted a few seconds. No one Else smelled it. It disapeared as fast as it came. Could this have been epileptic seizures? I am on prozac 80 mg and abilify 7 mg.

Many people will experience an aura prior to a seizure which can include visual or smell sensations.

However, I don't believe they are specific.

Have you had seizures in the past?  What else happens around the time you're having an aura?  Sometimes a seizure can be just a brief loss of consciousness that you may not be aware of.  Have other people noted you zoning out, or perhaps a brief loss of coordination when doing an activity such as walking riding a bike, or driving?  Ever?  Around the time of the auras?

What are you doing at the time of the aura?  Sometimes I'll get a whiff of sulfur in a shower that doesn't seem to be there all the time.

Discuss your symptoms with your physician.  Certainly watch for changes intensity or frequency of your symptoms.  And, avoid jobs that would endanger yourself or others if you were to have a Absence seizure recurrence.  If you are driving and have it, then by all means find a place to safely stop your car.

Notes of seizures and Prozac (Fluoxetine) seem ambiguous.
Seizures: Fluoxetine should be used with caution in patients with a history of convulsive disorders. The incidence of seizures associated with fluoxetine during clinical trials did not appear to differ from that reported with other marketed antidepressants; however, patients with a history of convulsive disorders were excluded from these trials.

I'm seeing similar notes with abilify.
Abilify may increase the risk of seizures. Before starting Abilify, tell your healthcare provider if you have epilepsy or a history of seizures.

It sounds like the risk is not high with low doses, but apparently most antidepressants can be associated with seizures.  It is especially common with overdoses, but may also occur with low doses.

Unfortunately, twice a year is difficult to judge frequency if you have an aura.  When did you start taking the antidepressants?  Did you have the auras/seizures between early childhood and when you started taking the antidepressants?  When was the last true seizure?  Anyway, if you cut out the antidepressants and have no more auras, you really won't know for sure if that was fate, or the antidepressant was causing them.

Medications , (apparently including Abilify and Prozac), can cause olfactory hallucinations ...

Quote
On Sep, 5, 2013: 26,130 people reported to have side effects when taking Abilify.
Among them, 8 people (0.03%) have Hallucination, Olfactory.
http://www.ehealthme.com/ds/abilify/hallucination,+olfactory

But that the false sensation of smell only lasted a few seconds is more in keeping with a focal (partial) seizure ...

NB: loss of consciousness will not necessarily occur with focal (partial) seizure ...

Quote from: wikipedia.org/wiki/Partial_seizure
In simple partial seizures a small part of one of the lobes may be affected and the person remains conscious

I was starting taking prozac for 3 weeks ago. I started taking 80 mg for about 1/2 week ago. I had no seizures between childhood to before i began taking prozac. The last true seizure was when i was about 12 year, when i took milk in a glass and overfilled the glass bechause I had a abcence seizure I think.

One night I stood up, wisstled a little and took my digital clock up in bed, and i only remember parts of it. And tonight I sat up and it looked like I saw sonething in the bed that wasnt there bechause I did something with my hand. Can those things have been seizures?

Possibly, but it sounds more like some kind of Parasomnia event.  I know that while I was a child, my parents could wake me up, ask me questions, then I'd fall back asleep with absolutely no recollection of the events in the morning.

How long have you been taking the abilify?  Were these two aura events in the last few weeks, or throughout the whole year?

Why are you taking both prozac and amblify?

I found this:
Interactions between your selected drugs
fluoxetine ↔ aripiprazole

Applies to:Prozac (fluoxetine) and Abilify (aripiprazole)

FLUoxetine may increase the blood levels and effects of ARIPiprazole. This can make you more likely to develop side effects such as drowsiness, seizure, Parkinson-like symptoms, abnormal muscle movements, and low blood pressure. [...]

It sounds like both Prozac and Abilify are metabolized by the CYP2D6 enzyme, and thus compete for the same metabolic pathway.  Therefore adding one or the other could increase the serum amount of both drugs. 

They do have different mechanisms in the brain, so other than dosage considerations, there may not be any absolute contraindication for taking both.  Did you decrease the dose of the Abilify when you added the Prozac?

If your auras or partial seizures have occurred without the Prozac, then it probably isn't the cause, other than potentially making them worse or more common if the dosages of medications aren't carefully controlled.

One night I experienced that half of my body was almost paralysed.

If it's one side of your body, rather than your complete body, then my money is on focal seizure rather than sleep paralysis in parasomnia ...

Quote from: wikipedia.org/wiki/Sleep_paralysis
Sleep paralysis is a phenomenon in which people, either when falling asleep or wakening, temporarily experience an inability to move. More formally, it is a transition state between wakefulness and rest characterized by complete muscle atonia (muscle weakness).
https://en.wikipedia.org/wiki/Sleep_paralysis

Quote from: epilepsy.org.uk/info/seizures/focal-partial
The parietal lobes are responsible for your bodily sensations. Focal seizures in this part of your brain cause strange physical feelings. A tingling or warm feeling down one side of your body is typical. These types of seizures are also known as ‘sensory’ seizures.
http://www.epilepsy.org.uk/info/seizures/focal-partial

Just a thought : the symptoms you are being prescribed Prozac & Abilify for could actually* be due to epilepsy which can cause sufferers to experience strong emotions without an external trigger : they can feel euphoric or dread without an exogenous reason ...

Quote from: epilepsy.org.uk/info/seizures/focal-partial
Here are some common symptoms of focal seizures in the temporal lobes ...
Feeling frightened, panicky, sad or happy
http://www.epilepsy.org.uk/info/seizures/focal-partial

If that is the case then you should discuss epilepsy medications with your healthcare provider,
as they could be more effective at reducing all your symptoms than your current medications.

Still could be due to partial (focal) seizure ...
Quote from: nih.gov
Partial seizures presenting as panic attacks

Panic disorder and some partial seizures may have similar symptoms. Patients with epilepsy may have prodromal symptoms of tension, anxiety, and depression. Temporal lobe seizures commonly include affective symptoms, fear, and autonomic features, including changes in skin colour, blood pressure, and heart rate. In comparison, for panic attack to be diagnosed (Diagnostic and Statistical Manual of Mental Disorders, fourth edition) patients must have at least four of 13 symptoms, including physical symptoms (palpitations, sweating, trembling, sensation of breathlessness, chest pain, feeling of choking, nausea, faintness, chills or flushes, and paraesthesiae) and affective symptoms, including fear of losing control, fear of dying, and derealisation or depersonalisation.  There is, therefore, considerable overlap of symptoms between the two disorders ...

... videotaping has the advantage of recording a patient's behaviour during an attack,
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1118775/

Maybe show your doctor highlights of your videos of your movements , which could be diagnostic [ automatisms ].

Quote from: bbc.co.uk
Dr John Duncan is a neurologist and medical director of the National Society for Epilepsy.

He said: "The key really is in the training and the use of videotape material has proven to be very useful over the years.

"Nowadays we're developing training programmes for both general physicians and specialist neurologists showing them whole ranges of videotapes showing them clips of epileptic seizures and episodes that are non-epileptic and teaching them to tell the difference between the two."
